1.2 Transportation Considerations

(1) The OVAL ﬂowmeter can best be transported to the installation site in the shipping container used for

transit from the factory.

(2) Avoid impact shocks during transit.

1.3 Storage Considerations

If the meter is to be stored for extended periods of time upon receipt before installation, unexpected problems could arise. If such is the case, the following considerations should be taken:

(1) The ﬂowmeter can best be stored in the original package used for transit from the factory.

(2) The place of storage should meet the following requirements:

󱾀 Free from rain and water 󱾀 Free from vibration and impact shock 󱾀 Storage/shipping conditions Temperature：20±15℃ Relative humidity：65±20％ Barometric pressure：500 to 1060hPa

1.4 Operating Conditions

In order to maintain the designed metering accuracy and long service life, it is essential that the ratings, such as the ﬂow rate, pressure, and temperature be kept within the speciﬁed limits. These operating conditions are stated in Sections "3. SPECIFICATIONS AND PERFORMANCE" and "13. PRODUCT CODE EXPLANATION" of this manual. Make sure to fully understand them before placing the meter in service.

◦ If the process ﬂuid is corrosive, the meter materials must be reviewed for compatibility. ◦ Cleanse the interior of flow tube thoroughly after use for measuring fluids that tend to deposit

solids. If solid deposits adhere to ﬂow tube, it can affect the meter accuracy.

◦ If you need to change operating conditions, consult OVAL. ◦ Some gasmixtures that are not homogeneous cannot be measured. Consult OVAL for applicability.

1.5 Precautions at Installation

CAUTION:

To ensure accurate and stable measurement, the Coriolis ﬂowmeter should be

installed in a location where piping vibration will not exceed 0.3G.

1.6 Precautions for power-on

Be sure to close the display lid and the terminal lid of the transmitter before turning on the power. The explosionproof enclosure must be ensured (with the requirements stated in section 10.5 satisﬁed) before use. To ensure the stable measuring condition, allow 20 minutes of warm-up period. "WARM UP 20" will be displayed for 20 minutes after powering-on. The number indicates remaining warm-up period (min.).

1.7 Returning Equipment

If the meter must be returned to OVAL for any reason, follow these steps to ensure the most efficient processing.

(1) Clean the unit and ﬂush out the ﬂow tube and pack the sensor unit carefully. Fully document the ﬂuid.

Inadequate information will delay handling of the meter. (⇨ Fill in the forms prepared on pages 96 and 97.)

(2) Enclose complete information about the contents being returned including model and serial numbers,

the reason for return, return address, and full documentation of the type of ﬂuid in writing.

(3) Pack the equipment carefully, using the original packing if possible.

(4) Return the complete ﬂowmeter, including, for instance, the transmitter with all associated components.

Remove the conduit connections and all other parts not originally shipped with the meter (for example, wiring connections).

Be sure to completely remove any foreign matter inside the sensor unit . Because the sensor unit cannot be disassembled, OVAL will not be able to clean residue inside the tube and service your meter.

CAUTION:

1. Since the casing of sensor unit is not pressure resistant, the withstanding pressure rating of the casing is not indicated. To afford adequate protection to personnel, an Rc 1/4 boss is

provided in an area shown in Fig. 4.1; Use customer's discretion in providing a rupture disc, pressure switch, etc. Rupture disc pressure rating and pressure switch setting is 7 MPa (G). A precaution to remember: removing the Rc 1/4 plug with the boss pointing downward may result in the leakage of inert argon gas. In this case, reﬁll with an inert gas, such as argon. For further details of treatment, consult OVAL.

2. Density measurement and volumetric ﬂowmetering are unacceptable.

3.1.3 Pressure Loss

◎How to determine pressure loss (liquids only) (1) Find the pressure loss coefﬁcient C from the ﬂow rate (kg/h) and viscosity of parameter (mPa・s). Dividing this

value C by speciﬁc gravity d (1 for water) gives the pressure loss, thus

(2) For high-viscosity liquids not shown in the graph, calculate the pressure loss by using the following equation:

where ΔP2 : Pressure loss of high-viscosity liquid (MPa) μ2 : Viscosity of high-viscosity liquid (mPa･s) d : Speciﬁc gravity of high-viscosity liquid (1 for water) μ1 : Maximum viscosity shown in the graph (mPa･s) C : Pressure loss coefﬁcient found from the maximum viscosity curve at a given ﬂow rate (kg/h) (3) For pressure loss of gases, consult OVAL.

5. INSTALLATION

5.1 Considerations at Installation

(1) Select a location easy to access for inspection and maintenance.

(2) Avoid locations subject to severe temperature variation and vibration.

(3) Avoid direct exposure to the sun. (Provide a sunshade or visor if necessarry.)

(4) Avoid locations where there is a risk of immersion in water.

(5) Select a location free from an atmosphere of corrosive gases.

(6) Location should be free from dust and mist.

(7) Keep a distance of at least one meter from sources of electr omagnetic induction, such as la rge

transformers and motors. Install sufﬁciently away from motors, pumps, or other sources of high vibration.

(8) To ensure consistent and accurate measurement, adhere to the instructions for tubing clamps on page 16.

(9) To ensure accurate and consistent measurement, use the Coriolis ﬂowmeter in a location where piping

vibration is kept below 0.3G.

(10) Instal the control valve downstream of the ﬂowmeter.

Where cavitation may possibly occur, install the valve at least ﬁve meters away from your meter.

5.2 Physical Orientation

Physical orientation does not affect the performance of this unit. It can be installed either in a horizontal or vertical run. However, with metered ﬂuids that tend to produce bubbles and/or sediments, or where process ﬂuid removal or purging is conducted after measurement, install the unit in a vertical run.

(1) A Coriolis mass ﬂowmeter is unaffected by the

ﬂow pattern of process ﬂuid.

T h e r ef o r e , it do e s no t r e q ui r e a n y fl o w

straighten e r. Howeve r, c o n n e c tion w i t h a deformed pip e re quires use of a con centric reducer or tapered pipe.

(2) Locate the meter sufﬁciently away from known

sources of vibration and pulsation.

(3) For zeroing, provide a valve that can stop the

flow completely downstream of the meter. We recommend to provide another valve upstream of the meter for servicing.

(4) Avoid piping stress concentration on the sensor.

CAUTION:

Although this meter is designed for installation on a mounting base, piping

clamps must be provided both upstream and downstream of the meter.

L-737-3-E

5.3.2 Inﬂuences of Vibration and Pulsations

Generally, Coriolis mass flowmeters can best make measurements with minimal pipeline vibration and pulsations. In applications where vibration and pulsations are not negligible, take the following measures:

(1) Locate the meter sufﬁciently away from the sources of vibration and pulsations.

(2) Provide attenuators, such as ﬂexible tubes and chambers. However, if this meter itself is the very source

of transmitting vibration to these elements during its operation, a drift in zeroing may result.

To get around this problem, take necessary countermeasures by, for example, locating such elements of

vibration sufﬁciently apart from the meter.

(3) Close shutoff valves upstream and downstream of the meter at process ﬂow shutdown. (For the sake of

preventing erratic signal generation at shutoff, be sure to prevent pressure buildup inside from exceeding the max. allowable pressure of the meter.)

(4) If meters of the same kind are to be installed in the same tubing, locate them sufﬁciently apart (at least 5

times the face-to-face length across the meter) and secure each meter with sturdy supports.

5.3.3 Prevention of Cavitation

Cavitation can cause a loss of meter accuracy in measurement. Maintain line pressures that will not cause cavitation upstream and downstream of the meter for this reason. Avoid making such an arrangement as to open the line to the atmosphere immediately downstream of the meter. Care must be exercised particularly in handling liquids of low steam pressure.

In practice, recommended minimum back pressure (pressure on the downstream side) of the meter is calculated by the formula:

Pd＝3ΔP＋1.3Pv

Where Pd : Downstream pressure (MPa [absolute]) ΔP : Pressure loss across the ﬂowmeter (MPa)

Pv : Steam pressure at the temperature during measurement (MPa [absolute])

5.3.4 Prevention of Excessive Flow Rate

CAUTION:

Exceeding the meter's maximum flow rate will not significantly reduce the

meter's long term durability. However, the output will be held at 110% of the allowable full scale ﬂow rate.

5.3.5 Keeping the Sensor Unit Completely Filled

CAUTION:

The sensor must be ﬁlled with the process ﬂuid during measurement.

A partially ﬁlled sensor unit results in large errors particularly at zeroing.

5.3.6 Bypass Line

For maintenance and servicing, it is good practice to provide a bypass loop.

5.6 Securing the Sensor Unit and Piping Clamps

To ensure accurate and consistent measurement, observe the following guidelines:

This is particularly important in applications where excessive piping vibration is observed, or during low ﬂow measurement.

◦Secure adequate rigidity between the mounting base and piping clamps both upstream and downstream. ◦Ensure rigid installation of piping clamps without using cushioning materials, such as rubber pads. ◦Secure adequate rigidity of the piping assembly itself from the sensor unit to piping clamps. ◦A change in the spring elements in the area surrounded by dotted lines may cause zero drift.

The sensor unit and mounting base are secured with four M10 bolts (designed to prevent them from

loosening) when shipped from the factory. On the rare occasion you ﬁnd loose bolts, retighten them.

◦Secure the mounting base to a sturdy pedestal that is ﬁrmly ﬁxed to a place without vibration.

CAUTION:

Secure the sensor unit ﬁrmly to a sturdy pedestal through the mounting base,

using M12 bolts and nuts (customer to furnish). With possible inadequate seating of the mounting base on the pedestal in mind, OVAL furnishes eight sets of spherical washers and four sets of ﬂange nuts as standard accessories with the product. Use them in combination with M12 bolts.

5.7 Heat Insulation Work

In applications where the process ﬂuid is of low or high temperatures, only the sensor unit should be heat insulated. Do not insulate the adapter and terminal box. We recommend simple sensor lagging to facilitate inspection and maintenance. Exclude the transmitter electronics.

(1) Careful attention should be paid to the maximum permissible temperature when steam trace is applied.

Maintain the tracing temperature around that of the process ﬂuid (see General Speciﬁcations).

(2) If steam, warm water or oil is used, secure by spot welding the copper tubing, or of other material, to the

sensor unit when you spirally wrap the tubing around the sensor unit (Fig. 5.8).

NOTE: To minimize transmission of oscillation to the sensor, the spirally wrapped copper tubing should

start and end at locations as close to the connector as possible (see Fig. 5.8).

CAUTION:

Do not use electric heaters which can be a source of noise.

9.1.2 Switch operation

The transmitter has two infrared switches: "SEL" and "ENT". Operation of these switches is described here. For information about parameter configuration and other functions, see the respective sections. (1) "ENT" operation

This switch is used for scrolling the display, scrolling the cursor, etc. Here we cover "ENT" operation as an example of switching variables view screens.

① Touch ENT key at lower right of screen over glass faceplate with

your finger. When the key responds, a down arrow ▼ appears at lower right of screen (surrounded by a dotted circle) where nothing was found as shown in the next screen.

② After down arrow comes on for 0.5 sec, arrow ▼ is highlighted as

shown in the following screen.

③ While the highlighted arrow stays on (0.5s), remove your finger.

Arrow ▼ goes out and the screen changes. (With your finger held on, you can continue "ENT" operation. It is beneficial for fast scroll.)

④ End of "ENT" operation

The next screen appears.

(2) "SEL" operation

This operation is used to switch screen direction, increasing the number, parameter select, etc. Here we cover "SEL1" operation as an example of switching screen direction.

① Touch SEL key at lower left of screen over glass faceplate with

your finger. When the key responds, a letter S appears at right bottom of screen (surrounded by a dotted circle) where nothing was found as shown in the next screen.

9.8 Zeroing Function

This feature detects errors in zeroing and reduces offset flowrate drift to minimum. At the stage of installation and in cases where flow conditions significantly change, zeroing is an essential part of the routines required for maintaining accurate and consistent measurement. During the zeroing, fill the sensor unit completely with the fluid the temperature of which is within ±10℃

from the temperature at which it operates.

CAUTION: 1. Before using this function, close both the display lid and the terminal lid of

the transmitter and make sure that the transmitter is in the condition as the actual operating condition.

2. Fluid (liquid or gas) must completely fill the flow tube and be absolutely at zero flow.

3. Accurate zeroing cannot be achieved unless fluid flow is completely halted.

4. Ensure that the shutoff valve has no leaks.

Zero adjustment comes in three options: with LCD switches, with status input, and through communication. Each has identical functions. Choose one that best suits your task.

9.8.1 Through LCD display switches

(1) Bring up the item of function you want to use.

Firstly, proceed key operation to show Calibration (Auto Zero) screen. (For the procedure to view individual items, see 9.2.2 thru 9.2.7 Transition chart.) When the cursor is placed over zeroing (Auto Zero), click "SEL1" to bring up the next confirmation screen.

Click "SEL1".

Click "SEL3".

Click "ENT".

Click "SEL3".

Click "ENT".

(2) Confirm zero flow

Shut off valves before after the meter and verify that fluid flow is halted. Upon confirmation of steady state, click "SEL3" to proceed to the next screen. If fluid flow is not completely halted, click "ENT" followed by clicking "SEL3". Do not attempt zeroing. (Ensure zero flow once again before you perform zeroing.)

Click "ENT".

(3) Confirm precautionary notes during zeroing.

Performing zeroing overwrites previous zero setting. Reconfirm. If no problem is found, click "SEL3" to proceed to the next screen. If you want to reconfirm the state, click "ENT" followed by clicking "SEL3". Do not attempt to run zeroing. (Upon reconfirmation of the state, perform zeroing.)

Click "ENT".

9.8.2 Through status input signal

You can perform the zeroing with status input signal. Follow the procedure given below for preparation and operation:

(1) Preparation to assign status input to zeroing

・Set status input function to "Auto Zero".

(For details of setup, see 9.15 Status Input and 9.2.5 Transition chart (4) [No. 2-5-1].

・Set input mode of status input.

(For details of setup, see 9.15 Status Input and 9.2.5 Transition chart (4) [No. 2-5-2].

(2) Preparation to assign zeroing in progress to status output

(You can perform the zeroing without this setting. You may omit this procedure if not required.) By completing the settings that follow, you can monitor the zeroing status with status output.

・Set function assignment of status output to "Error Status". ・Set adjustment item of status output to "On". ・Set working output of status output. (For detail of setup procedure, see 9.14.3 Status output and

9.2.5 Transition chart (4) [No. 2-4-5-1], [No. 2-4-5-2-8], and [No. 2-4-5-3].

(3) Procedure to run the zeroing

By working with separately input, you can perform the zeroing. Follow the procedure outline below:

① Preparation

Verify the following precautions: During the zeroing, fill the sensor unit completely with the fluid the temperature of which is within ±10℃ from the temperature at which it operates.

CAUTION: 1. Fluid (liquid or gas) must completely fill the flow tube and be absolutely at

zero flow.

2. Accurate zeroing cannot be achieved unless fluid flow is completely halted.

3. Ensure that the shutoff valves, etc. have no leaks.

② Run the zeroing: set the status input to 0.3 sec or longer in the "Short" (when input mode is

"Short"). Upon detection of an input, the zeroing process starts and this process lasts in about 30 seconds.

In the event zeroing has failed, you cannot expect accurate measurement. Upon completion of zeroing, do not forget to run a check for possible errors.

9.8.3 Through Link Top communication

Zeroing can be conducted through communication, using the software Link Top. For detail of procedure, see the Link Top instruction manual.

NOTE:

This function is disabled in Write Protect mode (refer to section 9.2).

9.9 Analog Trim Function

NOTE:

This function is disabled in Write Protect mode (refer to section 9.2).

The transmitter is provided with two analog outputs. Both are factory adjusted and requires no further adjustment. However, if it is absolutely necessary to readjust, follow the instructions outlined below. Prior to making adjustment, connect required measuring instruments in place for making output level measurement of analog output. Covered below is the procedure to make 4mA trim of analog output 1 (trimming 4.1mA to 4mA in the example below). A similar procedure applies to other adjustments.

(1) Bring up the item of function you want to use.

Firstly, proceed key operation to show Trim Analog 1 screen (4mA trim of analog output 1). (For the procedure to view individual items, see 9.2.2 thru 9.2.7 Transition chart.) When the cursor is placed over 4mA trim of analog output 1, click "SEL1" to bring up 4mA trim screen of analog output 1.

9.12 Pulse Output Function

The transmitter is provided with two pulse outputs which can be set up as independent outputs. Attractive features include a double pulse output created by allowing two pulses out of phase by 90 or 180 degrees, and a bidirectional pulse output - linked with status output signal, enabling the operator to discriminate the direction of flow. Refer to the following topics for description of these features. (NOTE: When the pulse output assignment, full scale flowrate, or frequency at full scale is modified, the Counter/Totalizer will be reset.)

NOTE:

For this function, the setting change is disabled in Write Protect mode (refer to section 9.2).

9.12.1 Pulse output 1

If you want to use pulse output 1, it is required that the following be set up. For using bidirectional pulse output or double pulse output, be sure to set the assignment of interest.

(1) Setup procedure

① Pulse output 1 assignment (Assign) (See 9.2.4 Transition chart (3) [No. 2-4-3-1].)

Kind of flow is selected.

・Mass Flow: Mass flow ・Volume Flow: Volumetric flow

② Frequency of pulse output 1 at full scale flowrate (Freq Factor) (See 9.2.4 Transition chart (3)

[No. 2-4-3-2].) The frequency at the flowrate set in ③ is set up. Set it to match the measurable range of the instrument that measures pulse output. Acceptable setting range is from 0.1 to 10000Hz.

③ Full scale flowrate of pulse output 1 (Rate Factor) (See 9.2.4 Transition chart (3) [No. 2-4-3-3].) An output is generated at the frequency set in ② when the preset flowrate is reached. ④ Low flow cutoff of pulse output 1 (Lowcut) (See 9.2.4 Transition chart (3) [No. 2-4-3-4].)

When the proportion of flowrate is smaller than the low flow cutoff value - where the flowrate set in ③ is set to 100% - the output is clamped at 0. Acceptable setting range is from 0.0 to 10.0%.

⑤ The state of pulse output in an error (Pulse) (See 9.2.5 Transition chart (4) [No. 2-4-6-2].)

Pulse output value in an error can be selected from the following three options:

・Zero: Pulse output is halted. ・Hold: Pulse output immediately before an error is maintained. ・Upscale: 11kHz is output. (For detail of output in an error, see 10.1 Error Messages.)

9.12.2 Pulse output 2

If you want to use pulse output 2, it is required that the following be set up. For using bidirectional pulse output or double pulse output, be sure to set the assignment of interest. (In the case of double pulse output, set only pulse output 2 assignment. Invalidating parameters other than that, pulse output 2 is also output with the same setting as that of pulse output 1.)

① Pulse output 2 assignment (Assign) (See 9.2.4 Transition chart(3) [No. 2-4-4-1].) Type of flow to

be assigned is selected.

・Mass Flow: Mass flow ・Volume Flow: Volumetric flow ・Double pulse 90: Double pulse output 90° ・Double pulse －90: Double pulse output － 90° ・Double pulse 180: Double pulse output 180°

As for double pulse output, see 9.12.4 Double pulse output. As for ②, ③, and ④ below, a procedure similar to pulse output 1 applies. See 9.12.1 Pulse output (1).

② Frequency of pulse output 2 at full scale flowrate (Freq Factor) (See 9.2.4 Transition chart (3)

[No. 2-4-4-2].)

③ Full scale flowrate of pulse output 2 (Rate Factor) (See 9.2.4 Transition chart (3) [No. 2-4-4-3].) ④ Low flow cutoff of pulse output 2 (Lowcut) (See 9.2.4 Transition chart (3) [No. 2-4-4-4].) ⑤ The state of pulse output in an error (Pulse) (See 9.2.5 Transition chart (4) [No. 2-4-6-2].)

9.12.3 Bidirectional pulse output

By allowing status output signal to provide flow direction information, the transmitter distinguishes between pulse outputs in the forward and reverse flow, and counts up pulses independently. (Hence, it requires on the part of measuring instrument a circuit to distinguish the directions of flow.) To utilize this function, you need to set up the following in addition to settings of pulse outputs 1 and 2.

(1) Setup procedure

① Status output function assignment (Function) (See 9.2.5 Transition chart (4) [No. 2-4-5-1].)

・Select Bi Direction.

② Active output of status output (Mode) (See 9.2.5 Transition chart (4) [No. 2-4-5-3].)

Set the active output status of status output.

・Off Active: Output is in the Short in the forward fluid flow. ・On Active: Output is in the Open in the forward fluid flow.

(2) An example of settings and assignments

Status output function assignment (Function): Bi Direction Active output of status output (Mode): Off Active Pulse output 1 assignment (Assign): Mass Flow Frequency of pulse output 1 at full scale flowrate (Freq Factor): 1000 [Hz] Full scale flowrate of pulse output 1 (Rate Factor): 100.0 [kg/min] Low flow cutoff of pulse output 1 (Lowcut): 10.0 [%]

9.13 Analog Output Function

The transmitter is provided with two analog outputs which can be assigned to "mass flow", "volume flow", "temperature", "density" and "drive output". The setup procedure is outlined below:

NOTE:

For this function, the setting change is disabled in Write Protect mode (refer to section 9.2).

(1) Setup procedure

By reconfiguring the following five parameters, outputs that suit your particular application are made available.

① Output assignment (Assign) (See 9.2.4 Transition chart (3) [No. 2-4-1-1] and [No. 2-4-2-1].)

Types of measurement are selected.

・Mass Flow: Instant mass flowrate ・Vol Flow: Instant volume flowrate ・Density: Density ・Temp: Temperature ・Drive Output: Drive output

When assignments are modified, reconfigure upper limit, lower limit, low flow cutoff, and damping factor to values that best suit your application.

② Upper limit value (URV) (See 9.2.4 Transition chart (3) [No. 2-4-1-2] and [No. 2-4-2-2].)

The lower limit of analog output can be changed; a 4mA output is produced when the preset value is reached. Values outside the maximum range (※1) and smaller than the lower limit value are unacceptable, however.

③ Lower limit value (LRV) (See 9.2.4 Transition chart (3) [No. 2-4-1-3] and [No. 2-4-2-3].)

The upper limit of analog output can be changed; a 20mA output is produced when the preset value is reached. Values outside the maximum range (※1) and larger than the upper limit value are unacceptable, however.

④ Low flow cutoff (Lowcut) (See 9.2.4 Transition chart (3) [No. 2-4-1-4] and [No. 2-4-2-4].)

The low flow cutoff of analog output (%) can be changed. When the low flow cutoff value is larger than the proportion of analog output － where the upper limit is set to 100% and the lower limit is 0% － the analog output becomes 4mA. Acceptable setting range is from 0% to 10%.

⑤ Damping factor (Added Damp) (See 9.2.4 Transition chart (3) [No. 2-4-1-5] and [No. 2-4-2-5].)

Damping constant of analog output (sec) can be changed. Select a larger value when analog output fluctuates excessively; select a smaller value when fast response is desired. Acceptable setting range is from 0 to 200 (sec).

9.16 High/Low Alarm Function

The transmitter provides the operator with quick grasp of conditions of the installation － flowrate, temperature, density and total flow － when high/low alarms are set up. In the event the preset alarm conditions are met, it tells the operator the event with an alarm message along with a status output signal. Setup procedure and behavior of alarm functions are described below:

(1) Setup procedure

Ensure positive settings on individual items.

① Status output function assignment (Function) (See 9.2.5 Transition chart (4) [No. 2-4-5-1].)

To use high/low alarm function, it is essential to assign high/low alarms to status output. Set "H/L Alarm" to status output function assignment. ("H/L Alarm" setting is required even in cases of high alarm only or low alarm only.)

② Output mode of status output (Mode) (See 9.2.5 Transition chart (4) [No. 2-4-5-3].)

Set up the output mode of status output.

・Active output of status output: Off Active or On Active

(For detail of the status output function, see 9.14 Status Output Function.)

③ Assignment of H/L alarm values (Assign) (See 9.2.5 Transition chart (4) [No. 2-6-1].)

From the following options, select the variables against which the transmitter identifies alarmed conditions.

・Mass Flow: Instant mass flowrate ・Vol Flow: Instant volume flowrate ・Dens: Density ・Temp: Temperature ・Counter 1: Counter 1 ・Counter 2: Counter 2 ④ Alarm type selection (H/L Alm. Type) (See 9.2.5 Transition chart (4) [No. 2-6-2].)

Select alarm type from the following options.

・To validate only high alarm, select "High Alarm". ・To validate only low alarm, select "Low Alarm". ・To validate both high and low alarms, select t "H/L Alarm". ⑤ High alarm value setting (High Alm. Po.) (See 9.2.5 Transition chart (4) [No. 2-6-3].)

If the input exceeds this setting, the high alarm is activated. Set the high alarm value desired. In the case "Low Alarm" is set in ④, setting is not required.

⑥ Low alarm value setting (Low Alm. Po.) (See 9.2.5 Transition chart (4) [No. 2-6-4].)

・Low Alm. Po.: Low alarm value

In the case "High Alarm" is set in ④, setting is not required.

⑦ Hysteresis value setting for high/low alarms (H/L Alm. hys)

(See 9.2.5 Transition chart (4) [No. 2-6-5].) The setting determines a dead (or immunity) zone following the occurrence of an alarm. Select a larger value when measurement fluctuates excessively; select a smaller value if fast recovery from alarmed condition is desired.

NOTE:

For this function, the setting change is disabled in Write Protect mode (refer to section 9.2).

9.17 Gas Mixed Flow Alarm Function

If gases exist in large quantities in the process fluid, it is impossible to make accurate flow measurement. This feature, if correctly set up, detects gases entrapped in the fluid, indicates a slug flow alarm, clamps the flow signal at 0, and provides a status output telling the operator the alarm event. (If you want to use this function, set the higher limit density value of slug flow to 10 (default) and the lower limit density value of slug flow to 0 (default). This function then remains disabled.) The setup procedure of slug flow function is outlined below.

(1) Setup procedure

Ensure positive settings of individual items.

① Lower limit density of slug flow (Slug Low) (See 9.2.3 Transition chart (2) [No. 2-2-3].)

Upon detection of density smaller than this setting, the circuitry interprets it as slug flow and starts analysis. Set a value small enough with respect to the density expected for the fluid of interest.

② Higher limit density of slug flow (Slug High) (See 9.2.4 Transition chart (2) [No. 2-2-4].)

Upon detection of density larger than this setting, the circuitry interprets it as an error and starts analysis. Set a value large enough with respect to the density expected for the fluid of interest.

③ Slug flow identification time (Slug Duration) (See 9.2.5 Transition chart (2) [No. 2-2-5].)

It is the time required for the circuitry to identify the slug flow being outside the slug flow high/low limit and to issue a slug flow alarm (sec). Until this slug flow identification time expires, it retains the most recent and properly measured value. After the expiration of this preset time, the flowrate becomes 0.

④ If you want to assign this slug flow alarm in the status output function to the status output,

setting the following is required: (For detail of this output function, see 9.14 Status Output Function.) ・Status output function assignment: Error Status (See 9.2.5 Transition chart (2) [No. 2-4-

5-1].)

・Slug flow error select: On (See 9.2.5 Transition chart (4) [No. 2-4-5-2-7].) ・Active output of status output: Off Active or On Active (See 9.2.5 Transition chart (4)

[No. 2-4-5-3].)

NOTE:

For this function, the setting change is disabled in Write Protect mode (refer to section 9.2).
