3.3. Flow transmitter wiring

3.3.1. Cautions in wiring

(1) Use a special coaxial cable (FLYC) as a signal cable between the detector and flow transmitter (FSV). Do

not provide a junction or splice of the signal cable midway.

(2) The signal cable between the detector or flow transmitter should be run in metallic conduits. Upstream and

downstream signal cables may be put in the same conduit but, to avoid interference, do not put the power

cable together. (3) For output signal, use a shielded cable, where possible. (4) To avoid noise interference, do not put the cables together with heavy duty line or the like into the same

duct. (5) If a ground wire is included in the power cable, connect it to ground as it is. (6) A power switch is not provided on the instrument and must be mounted separately. (7) Seal unused wiring ports by furnished caps.

CAUTION

3.3.2. Applicable wires

Use the following cables.

 Power cable : 3-wire or 2-wire cabtyre cable (Allowable temperature: 65°C or more)

Nominal sectional area 0.75mm2 or more Outside diameter Ф11 m m

 Output signal cable : 2-wire or multi-wire cabtyre cable as required (Allowable temperature: 65°C or more)

Outside diameter Ф11 m m

 Detector-flow transmitter cable : Signal cable by type designation

In case of detector FSSA : High-frequency coaxial double shield cable with

FSSC characteristic impedance of 50Ω FSSD With one-side waterproof BNC connector FSSH Outside diameter Ф7.3mm

In case of detector FSSE High-frequency coaxial double shield cable with

characteristic impedance of 50Ω

Outside diameter Ф7.3mm

3.3.3. Treatment of wiring port

The casing of the flow transmitter is IP66 and IP67. However, if installed in a humid place, the wiring ports must be made airtight to avoid ingress of moisture, condensation, etc. Be sure to use the waterproof glands furnished with the instrument in order to ensure the waterproof means. A gland, which is not ready to be used, should be sealed by supplied cover.

CAUTION

Do not install the instrument where there is a risk of flooding.

About the change of parameter setting When you change parameters of converter in current use which analog output or alarm has been set, if you change items which affect to the output or alarm, the output may change suddenly after display of "**COMPLETE**" and may generate alarm. If, especially, the output signal is being used for control, perform the signal lock on the system side prior to changing parameters.

Caution on change of parameter setting When you change parameter settings, parameters will be saved in non-volatile memory on return to measuring display. Saved parameters have been maintained even power is off. However, when you change the parameter and turn off the power before returning to the measuring display, parameters will not be saved. Thus you should set the parameter again.

4.9.2. Setting the total(actual)

4.9.2.1. Setting the total pulse (total rate, pulse width)

Description

Set to totalize a process variable (flow rate) by total meter, etc. according to total pulse output.



Total rate : Total amount (volume) per pulse.



A pulse is outputted when the total volume has attained an amount set by the pulse value, and adds to the total pulse count (in case of total pulse indication). Settable range: 0.000001 to 99999999 * Set the total unit before setting the pulse value. (See Section 4.8.3.)

Pulse width: Width of total pulse output.



Select a pulse width according to a corresponding total meter out of menus. Settable range: 5ms, 10ms, 50ms, 100ms, 200ms, 500ms, 1000ms.

Restrictions in the setup



Output of total pulses involves the following restrictions depending on the DO output port (DO1 and DO2).

DO output port Frequency range of pulse output

(at full scale flow rate)

DO1, DO2: Transistor, open collector 100 pulse/sec 5ms, 10ms, 50ms, 100ms, 200ms

The maximum output frequency is also restricted by the setup of the pulse width. Therefore, set the pulse width and pulse value so that both of condition 1 and condition 2 indicated below are satisfied. Correct results may not occur, if any setup that does not satisfy both of condition 1 and condition 2 is made.

Condition 1:

FULL SCALE

TOTAL RATE [m

Condition 2:

 100[Hz]



2 × PULSE WIDTH [ms]

1000

Note 1) The range of FULL SCALE1 or FULL SCALE2, whichever is larger, is the object in the case of automatic 2-range setup,

forward and reverse range setup or forward and reverse automatic 2-range setup.

Note 2) The output frequency on the output ports is limited when the flow rate exceeds the set range. Therefore, if such a setup that

the maximum frequency per range occurs at the time of 100% flow rate, there is possibility that the total pulse output will be incapable of following when the flow rate exceeds 100%, and accurate total value cannot be obtained if over-range continues for a long time. If there are cases where the flow rate exceeds 100%, modify the set range and pulse value so that the maximum frequency will not exceed the restricted level.

Example of calculation

Calculate the range that permits setup of the total value under the range and pulse width indicated below. When the range and the pulse width are as follows.

FLOW SPAN -1: 36[m

Condition 2

TOTAL RATE  FULL SCALE [m3/s] ×

2 × PULSE WIDTH [ms]

1000

The settable range of the total value that satisfies both of condition 1 and condition 2 is as follows from results of calculation A and B.

1 [L]  TOTAL RATE

Note) When the total setting value is “0”, total pulse is not output. Note) When setting, stop status is set at the total mode.

For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)

1. Incomplete installation

 Error in piping specifications  Sensor is mounted on

welding.

 Error in sensor mounting

Upon checking, remove the sensor, apply acoustic coupler, and slightly off position the sensor.

dimensions

 Error in acoustic coupler at

the time of mounting the sensor

 Error in connection of the

sensor cable.

Sensor mounting is poor

 Mounting dimension  The sensor is coming off the

pipe.

 Mount the sensor in parallel with

pipe, allowing correct sensor unit spacing.

 Mount the sensor properly so that it

is kept in close contact with the pipe.

2. Problem on pipe or fluid



Pipe not filled with fluid

Locate a place which is completely filled on the same piping line, and shift the sensor there.  Attach the sensor to the lowest place

on the pipeline.



Bubbles present in the fluid

Bubbles are introduced if reading

is normal when flow is stopped.

Eliminate ingress of bubbles.

 Raise the level of the pump well.  Check the shaft seal of the pump.

If mounted immediately

downstream a valve, a cavitation causes the same phenomenon as when bubbles are introduced.

 Retighten the flange of negative

pressure pipe.

 Arrange so that fluid doesn’t fall into

the pump well. Move the sensor to the location where air bubbles have not entered.

 Inlet side of the pump  Upstream side of the valve
