QUICK INSTALL

This manual contains detailed operating instructions for all aspects of the FSR Series. The following condensed instructions are provided to assist the operator in getting the instrument started up and running as quickly as possible. This pertains to basic operation only. If specic instrument features are to be used or if the installer is unfamiliar with this type of instrument, refer to the appropriate sec tion in the manual for complete details.

Note: The following steps require informati on supplied by the meter itself, so it is necessary to supply power to the unit, at least temp orarily, to obtain setup informatio n.

1 - Transducer Location

1. In general, selec t a mounting location on the piping system with a minimum of 10 pipe diameters (10x the pipe inside diameter) of straight pipe upstream and 5 straight diameters downstream. See Table 2.1 for additional congurations.

2. Select a mounting method for the transducers based on pipe size and liquid characteristics. See Table 2.2. Transducer congurations are illustrated in Figure Q.1 below. The V-mount conguration is usually the rst choice, with W-mount and Z-mount used if needed to boost signal strength.

Note: All FST1xxxx, FST2xxx x, and FST3xxxx transducers use V-Mount congu ration.

3. Enter the following data into the meter via the integral keypad or the software utility (if not entered by the factory)

INSTALLATION GUIDE

2 - Electrical Connections

Transducer/Power Connections

1. Route the transducer cables from the transducer mounting location back to the enclosure. Connect the transducer wires to the terminal block in the enclosure.

Note: Do not cut transducer cables to alter length. This will void the factory warranty. Cables are available in several lengths. Assess the installation location prior to ordering to determine the optimum length. If the wrong length is ordered, contact the factory.

2. Verify that power supply is correct for the meters power option.

AC units require 95 to 265 VAC, 47 to 63 Hz @ 17 VA maximum. DC units require 10 to 28 VDC @ 5 Watts maximum.

INTRODUCTION

General

The Veris ultrasonic ow meter is designed to measure the uid velocity of liquid within a closed conduit. The transducers are a non-contacting clamp-on or clamparound type that does not foul and is easy to install.

The Veris family of transit time ow meters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specic distance from each other. The transducers can be mounted in V-Mount where the sound transverses the pipe two times, W-Mount where the sound transverses the pipe four times, or in Z-Mount where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. The selection of mounting method is based on pipe and liquid characteristics that both have an eect on how much signal is generated. The ow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers. The dierence in the time interval measured is directly related to the velocity of the liquid in the pipe.

INSTALLATION GUIDE

Because the transducers are non-contacting and have no moving parts, the ow meter is not aected by system pressure, fouling, or wear. FST4 and FST5 transducers are rated to a pipe surface temperature of -40 to +250 °F (-40 to +121 °C). FST1, FST2, and FST3 small pipe transducers are rated from -40 to +185 °F (-40 to +85 °C).

PART 1 - MONITOR INSTALLATION

After unpacking, save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately.

Mount the enclosure in an area that is convenient for servicing, calibration, and observation of the LCD readout.

1. Locate the monitor within the length of transducer cables supplied. If this is not possible, it is recommended that the cable be exchanged for one that is of proper length. If additional cable is added, utilize RG59 75 Ω coaxial cable and BNC connections. Transducer cables that are up to 990 feet (300 meters) can be accommodated.

2. Mount the monitor in a location:

• Where little vibration exists.

• That is protected from corrosive uids.

• That is within the monitor’s ambient temperature limits -40 to +185°F

(-40 to +85°C).

• That is out of direct sunlight. Direct sunlight may increase monitor temperature to above the maximum limit.

3. Mounting - Refer to Figure 1.2 for enclosure and mounting dimension details. Ensure that enough room is available to allow for door swing, maintenance and conduit entrances. Secure the enclosure to a at surface with two appropriate fasteners.

INSTALLATION GUIDE

Transducer Connections

To access terminal strips for wiring, loosen the two screws in the enclosure door and open.

Guide the transducer terminations through the monitor conduit hole located in the bottom-left of the enclosure. Secure the transducer cable with the supplied conduit nut (if exible conduit was ordered with the transducer).

The terminals within the unit are of a screw-down barrier terminal type. Connec t the appropriate wires at the corresponding screw terminals in the monitor. Observe upstream and downstream (+/–) orientation. See Figure 1.3.

PART 2 - TRANSDUCER INSTALLATION

INSTALLATION GUIDE

General

The FST transducers contain piezoelectric crystals for transmitting and receiving ultrasonic signals through walls of liquid piping systems. FST transducers are relatively simple and straightforward to install, but spacing and alignment of the transducers is critical to the system’s accuracy and performance. Take care to ensure that these instructions are carefully executed. FST1, FST2, and FST3 small pipe transducers have integrated transmitter and receiver elements that eliminate the requirement for spacing measurement and alignment.

Mounting of the FST4 and FST5 clamp-on ultrasonic transit time transducers is a three-step process:

1. Select the optimum location on a piping system.

2. Enter the pipe and liquid parameters into either the sof tware utility or key the parameters into the transmitter using the keypad. The software utility or the monitor’s rmware calculates proper transducer spacing based on these entries.

3. Pipe preparation and transducer mounting.

BTU meters require two RTDs to measure heat usage. The ow meter utilizes 1,000 Ω, three-wire, platinum RTDs in two mounting styles. Surface mount RTDs are available for use on well insulated pipes. Mounting the RTD in an uninsulated area causes inconsistent temperature readings. Insertion (wetted) RTDs should be sued in these areas instead.

Step 1 - Mounting Location

The rst step in the installation process is the selection of an optimum location for the ow measurement to be made. This requires a basic knowledge of the piping system and its plumbing.

Diameters

An optimum location is dened as:

• A piping system that is completely full of liquid when measurements are being taken. The pipe may become completely empty during a process cycle, which results in the error code 0010 (Low Signal Strength) being displayed on the ow meter while the pipe is empty. This error code clears automatically once the pipe rells with liquid. It is not recommended to mount the transducers in an area where the pipe may become par tially lled. Partially lled pipes cause erroneous and unpredictable operation of the meter.

• A piping system that contains lengths of straight pipe such as those described in Table 2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. The straight runs in Table 2.1 apply to liquid velocities that are nominally 7 FPS (2.2 MPS). As liquid velocity increases above this nominal rate, the requirement for straight pipe increases proportionally.

• Mount the transducers in an area where they will not be inadvertently bumped or disturbed during normal operation.

• Avoid installations on downward owing pipes unless adequate downstream head pressure is present to overcome partial lling of or cavitation in the pipe.

• Note: Do not cut transducer cables to alter length. This will void the factory warranty. Cables are available in several lengths. Assess the installation location prior to ordering to determine the optimum length. If the wrong length is ordered, contact the factory.

Table 2.1 - Piping Conguration and Transducer Positioning

The ow meter system provides repeatable measurements on piping systems that do not meet these requirements, but accuracy of these readings may be inuenced to various degrees.

Step 2 - Transducer Spacing

Transit time ow meters can be used with two dierent transducer types. Meters that utilize the FST4 and FST5 transducer sets consist of two separate sensors that function as both ultrasonic transmitters and receivers. FST1, FST2, and FST3 transducers integrate both the transmitter and receiver into one assembly that xes the separation of the piezoelectric crystals. These transducers are clamped on the outside of a closed pipe at a specic distance from each other.

The FST4 and FST5 transducers can be mounted in:

W-Mount where the sound traverses the pipe four times. This mounting method produces the best relative travel time values but the weakest signal strength.

V-Mount where the sound traverses the pipe twice. V-Mount is a compromise between travel time and signal strength.

Z-Mount where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. Z-Mount will yield the best signal strength but the smallest relative travel time.

Table 2.2 - Transducer Mounting Modes — FST4, FST5

For further details, reference Figure 2.1. The appropriate mounting conguration is based on pipe and liquid characteristics. Selection of the proper transducer mounting method is not entirely predictable and many times is an iterative process. Table 2.2 contains recommended mounting congurations for common applications. These recommended congurations may need to be modied for specic applications if such things as aeration, suspended solids, out of round piping or poor piping conditions are present. Use of meter diagnostics in determining the optimum transducer mounting is covered later in this section.

Step 3 - Entering Pipe and Liquid Data

The system calculates proper transducer spacing by utilizing piping and liquid information entered by the user. Enter this information via the keypad or via the optional software utility.

The best accuracy is achieved when transducer spacing is exactly what the meter calculates, so use the calculated spacing if signal strength is satisfactory. If the pipe is not round, the wall thickness is not correct, or the actual liquid being measured has a dierent sound speed than the liquid programmed into the transmitter, the spacing can vary from the calculated value. If that is the case, place the transducers sat the highest signal level obser ved by moving the transducers slowly around the mount area.

Note: Transducer spacing is calculated on “ideal” pipe. Ideal p ipe is almost never found so the transducer spacing distances may need to be altered. An eec tive way to maximize signal strength is to congure the display to show signal strength, x o ne transducer on the pipe and then starting at the calculated spacing, move the rema ining transducer small distances forward and back to

nd the maximum signal s trength point.

Important! Enter all of the data on this list, save the data, and reset the meter before mounting transducers.

Before mounting the transducers onto the pipe surface, clean an area slightly larger than the at surface of each transducer to eliminate all rust, scale and moisture. For pipes with rough surfaces, such as ductile iron pipe, wire brush the surface to a shiny nish. Paint and other coatings need not be removed unless aked or bubbled. Plastic pipes typically do not require surface preparation other than soap and water cleaning.

Properly orient the transducers and spaced them on the pipe to provide optimum reliability and per formance. On horizontal pipes, when Z-Mount is required, mount the transducers 180 radial degrees from one another and at least 45 degrees from the top-dead-center and bottom-dead-center of the pipe. See Figure 2.2 Also see Z-Mount Transducer Installation. On vertical pipes the orientation is not critical.

Measure the spacing between the transducers using the two spacing mark s on the sides of the transducers. These marks are approximately 0.75” (19 mm) back from the nose of the FST4/FST5 transducers. See Figure 2.3.

Mount FST1, FST2, and FST3 transducers with the cable exiting within ±45 degrees of the side of a horizontal pipe. See Figure 2.2. On vertical pipes the orientation does not apply.

V-Mount and W-Mount Installation

Application of Couplant

For FST4 and FST5 transducers, place a single bead of couplant, approximately ½ inch (12 mm) thick, on the at face of the transducer. See Figure 2.4. Generally, a silicone-based grease is used as an acoustic couplant, but any grease-like substance that is rated not to “ow” at the temperature that the pipe may operate at will be acceptable. For pipe surface temperature over 130°F (55°C) Sonotemp® (P.N. D0022011-010) is recommended.

Transducer Positioning

1. Place the upstream transducer in position and secure with a mounting strap. Place straps in the arched groove on the end of the transducer. A screw is provided to help hold the transducer onto the strap. Tighten the transducer strap securely.

2. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 2.5. Apply rm hand pressure. If signal strength is greater than 5, secure the transducer at this location. If the signal strength is not 5 or greater then using rm hand pressure, slowly move the transducer both towards and away from the upstream transducer while observing signal strength. Clamp thetransducer where the highest signal strength is observed. Signal levels much less than 5 may not yield acceptable data.

Note: Signal strength readings upd ate only every few seconds, so it is advisable to move the transducer 1/8”, wait, see if signal is increasing or decreasing and then repeat unti l

the highest level is achieved.

3. If after adjustment of the transducers the signal strength does not rise to above 5, then select an alternate transducer mounting method. If the mounting method was W-Mount, then re-congure the monitor for V-Mount, move the downstream transducer to the new spacing distance and repeat Step 4.

Small Pipe Transducer Installation

The small pipe transducers are designed for specic pipe outside diameters. Do not attempt to mount a transducer onto a pipe that is either too large or too small for the transducer.

FST1, FST2, and FST3 installation consists of the following steps:

1. Apply a thin coating of acoustic coupling grease to both halves of the transducer housing where the housing will contact the pipe. See Figure 2.6.

1/16” (1.5 mm)

Acoustic Couplant Grease

Figure 2.6 - Application of Acoustic Couplant — FST1, FST2, FST3 Transducers

2. On horizontal pipes, mount the transducer in an orientation such that the cable exits at ±45 degrees from the side of the pipe. Do not mount with the cable exiting on either the top or bottom of the pipe. On vertical pipes the orientation does not matter. See Figure 2.2.

Spacing

Figure 2.5 - Transducer Positioning

3. Tighten the wing nuts or “U” bolts so that the acoustic coupling grease begins to ow out from the edges of the transducer or from the gap between the transducer halves. Do not over tighten.

4. If signal strength is less than 5, remount the transducer at another location on the piping system.

5. Conguration Procedure:

a. Establish communications with the transit tme meter. See Part 5 Software Utility.

Mounting Transducers in Z-Mount Conﬁguration

Installation on larger pipes requires careful measurements of the linear and radial placement of the FST4 and FST5 transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or inaccurate readings.

1. Place the transducers on opposite sides of the pipe. This distance around the pipe is calculated by multiplying the pipe diameter by 1.57. The transducer spacing along the pipe is the same as found in the Transducer Positioning section.

2. For FST4 and FST5 transducers, place a single bead of couplant, approximately ½ inch (12 mm) thick, on the at face of the transducer. See Figure 2.4. Generally, a silicone-based grease is used as an acoustic couplant, but any good quality grease-like substance that is rated to not “ow” at the temperature that the pipe may operate at is acceptable.

3. Place the upstream transducer in position and secure with a stainless steel strap or other fastening device. Place straps in the arched groove on the end of the transducer. A screw is provided to help hold the transducer onto the strap. Tighten transducer strap securely. Larger pipes may require more than one strap to reach the circumference of the pipe.

4. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 2.7. Using rm hand pressure, slowly move the transducer both towards and away from the upstream transducer while observing signal strength. Clamp the transducer at the position where the highest signal strength is observed. Signal strength of between 5 and 98 is acceptable. The fac tory default signal strength setting is 5, however there are many application specic conditions that may prevent the signal strength from attaining this level.

A minimum signal strength of 5 is acceptable as long as this signal level is maintained under all ow conditions. On certain pipes, a slight twist to the transducer may cause signal strength to rise to acceptable levels.

5. Certain pipe and liquid characteristics may cause signal strength to rise to greater than 98. At this level, the signals may saturate the input ampliers and cause erratic readings. To lower the signal strength, change the transducer mounting method to the next longest transmission path. For example, if there is excessive signal strength and the transducers are mounted in a Z-Mount, try changing to V-Mount or W-Mount. Finally you can also move one transducer slightly o line with the other transducer to lower signal strength.

6. Secure the transducer with a stainless steel strap or other fastener.

PART 3 - INPUTS/OUTPUTS

FSRxxxx SERIES

INSTALLATION GUIDE

General

The FSR1 is available in two congurations: the ow model and the energy model. The ow model is equipped with a 4-20 mA output, two open collec tor outputs, a rate frequency output, and RS-485 communications using the Modbus RTU command set. The energy version has inputs for two 1,000 Ω RTD sensors in place of the rate frequency and alarm outputs. This version allows the measurement of pipe input and output temperatures for calculating energy usage calculations.

4-20 mA Output

The 4-20 mA output interfaces with most recording and logging systems by transmitting an analog current signal that is propor tional to system ow rate. The 4-20 mA output is internally powered (current sourcing) and can span negative to positive ow/energy rates.

For AC powered units, the 4-20 mA output is driven from a +15 VDC source located within the meter, isolated from earth ground connections. The AC powered model accommodates loop loads up to 400 Ω. DC powered meters utilize the DC power supply voltage to drive the current loop. The current loop is not isolated from DC ground or power. Figure 3.1 shows graphically the allowable loads for various input voltages. The combination of input voltage and loop load must stay within the shaded area of Figure 3.1.

The ow rate output permits output changeover at two separate ow rates allowing operation with an adjustable switch deadband. Figure 3.5 illustrates how the setting of the two set points inuences rate alarm operation.

A single-point ow rate alarm places the ON setting slightly higher than the OFF setting, establishing a switch deadband. If a deadband is not established, switch chatter (rapid switching) may result if the ow rate is very close to the switch point.

Totalizer Output for Energy Meter

Energy units can be ordered with a totalizer pulse output option. This option is installed in the position where the Ethernet option would normally be; therefore, the totalizer pulse output option and the Ethernet communications output cannot be installed simultaneously.

Optional totalizing pulse specications:

Signal 1 pulse for each increment of the totalizer’s least signicant digit

Batch/Totalizer Output

Totalizer mode congures the output to send a 33 mSec pulse each time the display totalizer increments divided by the TOT MULT. The TOT MULT value must be a whole, positive, numerical value.

Fir example, If the totalizer exponent (TOTL E) is set to E2 (×100) and the totalizer multiplier (TOT MULT) is set to 1, then the control output pulses each time the display totalizer increments or once per 100 measurement units totalized.

Signal Strength Alarm

The SIG STR alarm provides an indication that the signal level reported by the transducers has fallen to a point where ow measurements may not be possible. It can also be used to indicated that the pipe has emptied. Like the rate alarm described previously, the signal strength alarm requires that two points be entered, establishing an alarm deadband. The ON value must be lower than the OFF value. If a deadband is not established and the signal strength decreases to approximately the value of the switch point, the output may “chatter.”

Error Alarm Outputs

When a control output is set to ERROR mode, the output activates when an error causes the meter to stop measuring reliably. See the Appendix of this manual for a list of potential error codes.

Frequency Output [FSRxxx1x only]

The frequency output is an open-collector transistor circuit that outputs a pulse waveform that varies proportionally with ow rate. This type of frequency output is also know as a “Rate Pulse” output. The frequency output is proportional to the max ow rate entered into the meter. The maximum output frequency is 1000 Hz.

In addition to the control outputs, the frequency output can be used to provide total information by use of a K-factor that relates the number of pulses from the frequenc y output to the number of accumulated pulses that equates to a specic volume.

This relationship is described by the following equation: K-factor = 60,000 / full scale units. The 60,000 relates to measurement units in volume/min. Measurement units in seconds, hours or days would require a dierent numerator.

If the frequency output is to be used as a totalizing output, then the meter and the receiving instrument must have identical K-factor values programmed into them to ensure that accurate readings are recorded by the receiving instrument. Unlike standard mechanical ow meters such as turbines, gear or nutating disk meters, the K-factor can be changed by modifying the MAX RATE ow rate value.

Note: For a full treatment of K-factors p lease see the Appendix of this manual.

There are two frequency output types available:

1.) Turbine meter simulation - This option is utilized when a receiving instrument is capable of interfacing directly with a turbine ow meter’s magnetic pickup. The output is a relatively low voltage AC signal whose amplitude swings above and below the signal ground reference. The minimum AC amplitude is approximately 500 mV peak-to-peak. To activate the turbine output circuit, turn SW4 OFF .

To interconnect meters, utilize three-wire shielded cable such as Belden® 9939 or equal. In noisy environments, connect the shield on one end to earth ground. Use a USB to RS-485 converter to communicate with a PC running Windows 98, Windows ME, Windows 2000, Windows NT, Windows XP, Windows Vista, or Windows 7. For computers with RS-232C serial ports, use an RS-232C to RS-485 converter to interconnect the RS-485 network to a communication port on a PC. If monitoring more than 126 meters, use an additional converter and communication port.

Heat Flow [BTU meters only]

The BTU meter allows the integration of two 1000 Ω, 3-wire, platinum RTDs with the ow meter, providing a means of measuring energy consumed in liquid heating and cooling systems. The RTDs are attached at the factory to a simple plug-in connector eliminating the possibility of mis-wiring. Simply install the RTDs on or in the pipe as recommended, and then plug the RTDs into the meter. The surface mount versions are available in standard lengths of 20 feet (6 meters), 50 feet (15 meters) and 100 feet (30 meters) of attached shielded cable.

The output is a square-wave with a peak voltage equaling the instrument supply voltage when the SW3 is ON. If desired, an external pull-up resistor and power source can be utilized by leaving SW3 OFF. Set SW4 to ON for a square-wave output.

RS-485

The RS-485 feature allows up to 126 metering systems to be placed on a single threewire cable bus. Each meter is assigned a unique numeric address that allows all of the meters on the cable network to be independently accessed. A Modbus RTU command protocol is used to interrogate the meters. An explanation of the command structure is detailed in the APPENDIX of this manual. Flow rate, total, signal strength and temperature (if so equipped) can be monitored over the digital communications bus. Baud rates up to 9600 and cable lengths to 5,000 feet (1,500 meters) are supported without repeaters or “end of line” resistors.

Installation of Surface Mount RTDs

Only use surface mount RTDs on well insulated pipe. Installing the RTD in an uninsulated area causes inconsistent temperature readings.

Select areas on the supply and return pipes to mount the RTDs. Remove or peel back the insulation all the way around the pipe in the installation area. Clean an area slightly larger than the RTD down to bare metal on the pipe.

Place a small amount of heat sink compound on the pipe in the RTD installation location. See Figure 3.11. Press the RTD rmly into the compound. Fasten the RTD to the pipe with the included stretch tape.

Installation of Insertion RTDs

Insertion RTDs are typically installed through ¼ inch (6 mm) compression ttings and isolation ball valves. Inser t the RTD suciently into the ow stream such that a minimum of ¼ inch (6 mm) of the probe tip extends into the pipe diameter. Only use insertion (wetted) RTDs on pipes that are not insulated.

Mount RTDs within ±45 degrees of the side of a horizontal pipe. On vertical pipes the orientation is not critical. Route the RTD cables back to the ow meter and secure the cable so that it will not be pulled on or abraded inadvertently.

If the cables are not long enough to reach the meter, route the cables to an elec trical junction box and add additional cable from that point. Use three-wire shielded cable, such as Belden® 9939 or equal, for this purpose.

Note: Adding cable adds to the resistance the meter reads and may h ave an eect on absolute accuracy. If cable is added, ensure that the same length is ad ded to both RTDs to minimize errors

due to changes in cable resistance.

Wiring to Meter

After the RTDs have been mounted to the pipe, route the cable back to the meter through the middle hole in the enclosure. Connect to the meter inserting the RTD connector into the mating connector on the circuit board.

PART 4 - STARTUP AND CONFIGURATION

Before Starting the Instrument

Note: Flow meter systems require a full pipe of l iquid before a successful start-up can be completed. Do not at tempt to make adjustmen ts or change congurations until a full pipe is veried.

Note: If Dow 732 RTV was used to couple the transducers to the pipe, the adhesive must be fully cured before readin gs are attempted. Dow 732 requires 24 hours to cure satisfactoril y. If

Sonotemp® acoustic coupling grease was utilized as a coupla nt, curing is not required.

INSTALLATION GUIDE

Instrument Startup

1. Verify that all wiring is properly connec ted and routed, as described in Part 1 of this manual.

2. Verify that the transducers are properly mounted, as described in Part 2 of this manual.

3. Apply power. The display briey shows a software version number and then all of the segments illuminate in succession.

Important!: In order to complete the installation of the ow meter, the pipe must be full of liquid.

To verify proper installation and ow measurement operation:

1. Go to the SER MENU and conrm that signal strength (SIG STR) is between 5 and

98. If the signal strength is lower than 5, verify that proper transducer mounting methods and liquid/pipe characteristics have been entered. To increase signal strength, if a W-Mount transducer installation was selected, re-congure for a V-Mount installation (standard from factory); if V-Mount was selected, recongure for Z-Mount.

Note: Mounting conguration change s apply only to FST4, FST5 transducer sets.

2. Verify that the actual measured liquid sound speed is within 2% of the value entered as FLUID SS in the BSC MENU. The measured liquid sound speed (SSPD FPS and SSPD MPS) is displayed in the SER MENU. The pipe must be full of liquid in order to make this measurement.

Keypad Programming

Congure units with keypads using the keypad interface or by using the Windows® compatible software utility. Units without a keypad can only be congured using the software utility. See Part 5 of this manual for software details. Of the two methods of conguration, the sof tware utility provides more advanced features and oers the ability to store and transfer meter congurations between meters. All entries are saved in non-volatile ash memor y and are retained indenitely in the event of power loss.

The four-key tactile feedback keypad interface allows the user to view and change conguration parameters used by the operating system.
