QUICK BENCH TEST:

Ultrason

Connect Sensor to the

T.DUCER terminals as shown below, then apply Power. When properly connected

a soft clicking can be heard from the sensor and figures will show on the large LCD display. Test operation of the Ultrason by holding the sensor steadily and aiming at a flat, stable target 12 to 28" (305 to 711 mm) away from the end of the sensor. Allow a few seconds for the Ultrason to lock onto the target before displaying its distance. The Ultrason will now display distance in ft or cm (factory calibration).

CONNECTIONS:

POWER INPUT: The standard model requires AC power input between 100-130VAC 50/60Hz (2 amp fuse is recommended). No adjustments are necessary for any voltage in this range. Optional 230VAC requires power input between 200-260VAC 50/60Hz. (See OPTIONS section of this manual for connection of optional 12VDC or 24VDC power input).

IMPORTANT NOTE

: To comply with CSA/NRTL standards, AC power input and relay connection

wires must have conduit entry to the instrument enclosure.

KEYPAD SYSTEM

The Ultrason has a simple 3-button calibration system. Operating and calibration modes are shown on the 16-digit alphanumeric display. The keypad is used to move around the menu to calibrate the Ultrason, and to view operating mode and functions. A beep is sounded as each key is pressed. If the keypad is not used for 2 minutes, the Ultrason will automatically go to

RUN mode (scrolling display). Use the

keypad to explore the Menu and become familiar with its features.

4-20mA CURRENT LOOP OFFSET

Some applications may require the 4-20mA output to be offset so that 4mA or 20mA corresponds to a Level, Range or Flow other than Zero and Full Scale.

4mA at - use Ç and È to set % output for 4mA. It is adjustable from -5% (3.8mA) up to 15% lower

than the 20mA setting. Adjustment resolution is 0.05% (0.01mA).

20mA at - use Ç and È to set % output for 20mA (down to 15% greater than the 4mA setting and up

to 300%). Adjustment resolution is 0.05% (0.01mA).

DAMPING

Minimum damping allows fast response to level changes. Increasing damping slows the Ultrason's response to level changes and is ideal to smooth the display and outputs in turbulent conditions. Damping value is shown in percent (0-99%). Some experimentation may be required to select the optimum damping value. A value of 20% is recommended for most applications. For fast level changes (up to ½ inch/sec - 13 mm/sec), a

Damping value of 1% is recommended. Maximum is 99%.

Ultrason

If the Ultrason is unable to obtain repeated echoes the Damping setting will be automatically set to 1% by the instrument.

REJECTION TIME (RejTime)

Rejection Time adjustment is a powerful Ultrason feature to suppress false echoes and the effects of transient targets such as agitators, splashing, or turbulence. Rejection Time is shown in seconds. The time value represents the number of seconds the Ultrason must receive repeated echoes from a new target before indicating its level on the display and outputs. The factory default is 8 seconds and should be ideal for most applications. Decreasing this value allows the Ultrason to respond more quickly to fast level changes, and increasing the time value allows the Ultrason to reject false echoes from slow sweeping agitators, tank filling streams, splashing, severe turbulence and steam. Minimum setting is 1 second (for fast level changes up to 1/2 inch/sec - 13 mm/sec). Maximum setting is 85 seconds. If the Ultrason is unable to obtain repeated echoes the by the instrument.

RejTime setting will be automatically set to 1 second

SENSOR MOUNTING/LOCATION

- Open Channel Flow Applications

Each sensor is equipped with a 3/4 inch isolation coupling which MUST be used in your installation. A threaded nipple or length of conduit may be used to position the sensor at the desired height. The sensor should be hand-tightened by turning the sensor stem only. DO NOT use a wrench and do not over tighten.

IMPORTANT: Follow the flume manufacturer’s directions for transducer location. The transducer should be centered above the flume approach section and mounted ³ 12"/30.5 cm (minimum) above the

maximum liquid level (depending on sensor model).

The transducer should be protected from physical damage and the transducer cable should be routed in a separate metal conduit.

Because the sensor is equipped with a temperature sensor, it should be shielded from direct sunlight.

Use the PVC “isolation coupling” supplied with the sensor and hand-tighten assembly onto your mounting stand. Do not

TYPICAL TRANSDUCER POSITIONING FOR FLUMES AND WEIRS

Always refer to the flume or weir manufacturer’s instructions for correct measurement point upstream from the flume or weir. Location of the sensor is critical for accurate flow measurement.

If manufacturer’s instructions are not available, the following guidelines are generally accepted.

1.PARSHALL FLUME:

Position the sensor at 2/3 Approach as illustrated above. Sensor height must be 12" (30.5 cm) or more above the highest water level.

2. PALMER BOWLUS FLUMES:

Position the sensor at 1/2 the flume Diameter upstream from the throat of the flume. Sensor height must be 12" / 30.5 cm (depending on sensor model) or more above the highest water level.

3. V-NOTCH WEIRS

Position the sensor at 3 x maximum Head upstream from the weir plate. Sensor height must be 12" / 30.5 cm (depending on sensor model) or more above the highest water level.

INSTALLATION CONSIDERATIONS IN NOISY ENVIRONMENTS

AquaMetrix’s instruments are designed with a high degree of noise immunity for use in industrial environments. Noise interference can still occur if certain minimal considerations are not adhered to when installing the equipment.

Noise

When relay contacts are used to switch inductive loads, such a auxiliary relays or solenoids, extremely large voltage spikes can be generated when the relay contact opens producing what is known as Radio-Frequency Interference or “RFI” or just “noise”.

These voltage spikes can also be coupled from power lines that are powering equipment that contains S.C.R. circuitry such as VSD controllers, or lines that are actuating AC or DC solenoids or actuators.

There are three major ways that noise spikes can enter the instrument.

1. Via the AC power input lines.

2. Via the Sensor input line.

3. Via the output lines (relay connections and 4-20mA output)

Ultrason

Symptoms of RFI produced by relay activation

If the instrument shows the following symptoms suspect RFI.

- The Alphanumeric display (bottom display) blinks continuously as if power was being turn off and on (i.e instrument resets continuously).

- Keypad does not respond or instrument resets to run mode from inside the menu.

- The instrument calibration is lost.

- The message "

- Relays trip erratically.

- Both digital displays go blank as if power was OFF.

Symptoms of noise on sensor input and/or 4-20mA lines

- Instruments readings are erratic or high when actual value is low

- The Alphanumeric display (bottom display) blinks continuously as if power was being turned off and on i.e instrument resets continuously.

- Instrument “beebs” intermittently even if the Keypad is not pressed.

MEM CORRUPTED" is shown.

Page 27

AquaMetrix

Ultrason

Avoiding noise problems

1. It is recommended that electronic instruments be connected to a relatively clean AC power source. Use an AC power filter or isolation transformer if necessary.

2. The sensor input line and the control lines (AC or DC) should not be run in the same conduit . The sensor input should be separated from wires going to inductive loads such as motors, solenoids, relays and contactors. For best results run the sensor wire in a separate metal conduit. A two-conductor shielded cable is recommended for the 4-20mA output, the shield should be connected to chassis ground at the instrument only.

3. For the relay connections, one of most overlooked sources of trouble, noise suppressors are recommended. Also known as “snubbers” these devices will limit the large spikes produced when the relay opens, stopping the RFI and also protecting the relay contacts from degrading.

APPENDIX B - APPLICATIONS BACKGROUND

Conditions in the tank or channel where the ultrasonic sensor is installed can affect the performance, range and accuracy of the system. The following notes are for general reference. Contact AquaMetrix or your local representative for specific information on your application.

Ultrason

FOAM ultrasonic level measuring system. Foam acts as a sound insulator and may eliminate, or reduce the strength of an echo. Measurement range may be reduced in a system where foam is present. Ultrasonics are not recommended where thick dense foam is continually present. Intermittent or thin layers of light foam (1/8 in. or less) can generally be disregarded. Use a stilling well in open channel applications.

LIQUIDS viscous liquids can be monitored without contacting the liquid.

SOLIDS - The Ultrason will measure most granular material and powders as well as liquids. Powders will not generally provide the same echo strength as liquids. Therefore maximum expected range should be reduced to approximately 20 feet (6 m) for powders. There are many exceptions to this rule and installation of a test system is recommended when in doubt.

DUST concentrations of dust are expected ultrasonics may not work. Where moderate dust is encountered care should be taken to mount the sensor in a position where dust accumulation will be minimized and where the sensor can be cleaned if necessary.

SENSOR TEMPERATURE - The standard sensor model US2 supplied with each Level & Flow Monitor includes a built-in temperature sensor. The Ultrason automatically compensates for temperature fluctuations to retain high accuracy. Note the operating temperature ranges listed in the product specifications section. Do not exceed the sensor temperature ratings or damage may occur.

ELECTRONICS TEMPERATURE specifications. Temperatures higher than the maximum shown can reduce the operating life of the electronics. Moisture condensation from those temperatures below the range shown can also damage electronics components. In cold or outdoor environments the optional factory-installed enclosure heater and thermostat is recommended.

NOISE vibration will not affect the system. Sensors installed in close proximity to one another in the same tank may “cross-talk” and should be synchronized.

VAPOUR can cause false echoes. Variable vapour cannot be compensated.

CHEMICAL COMPATIBILITY compatabilities. Tank contents should be checked for their compatibility with PVC. An all-teflon sensor is available for corrosive applications.
