Employ the Z method in the following cases.

• Mounting space need be saved (mounting space of the Z method is about one half of the V method's).

• Turbid fluid such as sewage is to be measured.

• Pipe has mortar lining.

• A thick film of scale may have been formed on the inner surface of pipe because it is old.

(2) Detector selection standards

The Z method for large size sensor is recommended for outer diameter 300mm or more. PSX2 D should be used as much as possible for pipes such as old pipes, cast iron pipes, and mortar lining pipes, through which it is difficult for ultrasonic signals to pass.

Determine the mounting position by carrying out the following work. For this work, gauge paper is necessary (For the gauge paper, refer to page 7-10).

q Match the edge of gauge paper with the line at

about 100mm from one end of the pipe portion treated for detector mounting, and wind the gauge paper so that the line marked on the paper is parallel with the pipe axis (fix with tape not to allow deviation). At this time, the edge of gauge paper should be aligned.

w Extending the line marked on the gauge paper,

mark straight line A on the pipe.

e Mark a line along on edge of the gauge paper.

The intersection of this line and straight line A is replaced with A

r In mounting by the V method, peel the gauge

paper and measure the mounting dimension from A0 to determine A2 position. At this position, mark a line orthogonal to the straight line A.

BULLETIN F-68

(1) Cleaning of converter and detector

Wipe off contamination, dust, etc. from the keyboard and main frame of the converter unit occasionally with soft cloth or the like. If contaminants cannot be removed by wiping with dry cloth, moisten cloth with water, wring it adequately and wipe again. Before accommodating the converter in the carrying case after use, wipe off grease completely. Note) Do not use volatile agents such as benzine and paint thinner for cleaning.

(2) When instrument unused

Put the instrument in the furnished carrying case and store it at a place which meets the following conditions.

• Not exposed to direct sunlight, rain, etc.

• Free from extremely high temperature and humidity (away from a heater)

Storage temperature: -10 to 45°C

• Absence of excessive dust and other contaminants.

(3) Replacement of memory backing battery

In normal usage, the battery has a service life of about 5 years. When the battery has reached the end of its service life, the data stored in memory will all be lost. For replacement, contact Dwyer Instruments.

(4) Replacement of LCD

LCD has a lifetime of 5 years or longer when used continuously. When display becomes difficult to be read or the backlight does not come on, the LCD should be replaced with a new one. For replacement, contact Dwyer Instruments.

(5) Replacement of built-in battery

The built-in battery can be charged up to about 500 times. If it cannot be charged, it is an indication that the battery life is terminated and it needs to be replaced. For replacement, be sure to use the battery specified by Dwyer Instruments.

(6) Replacement of printer roll-paper

When roll-paper is used for panel copy (hard copy), up to about 181 panels can be printed. When a red band appears on the roll-paper, it is an indication that little paper is left for printing. Replace with new one (OEM or equivalent: SEIKO Instruments; P/N: TP080-20LJ1).

BULLETIN F-68

11.1 Error in LCD Display

If an error occurs, refer to Table below.

Status

No display appears.

Irrational display

Display is not clear.

Cause Remedy

• Power supply is not turned on.

• Voltage is low.

• Fuse has blown.

• LCD is abnormal.

• Connection of DC power supply is reverse in polarity.

• Hardware error

•• Ambient temperature is high

(50° or higher) LCD has reached the end of its

service life.

• Line voltage is low.

• LCD is abnormal.

• Hardware error

Lower the temperature.

11 - 1

11.3 Error in measured value

BULLETIN F-68

State

Indication of measured value is negative (

Measured value fluctuated widely though flow rate is constant.

Measured value remains the same though flow rate is changing.

Cause

• Connection between the main unit and sensors (upstream sensor and downstream sensor) is reverse.

• Fluid is actually flowing in the (-) direction.

• Straight pipe portion is inadequate.

• A flow disturbing factor such as

pump or valve is provided in the vicinity.

• Pulsation is occurring actually.

• Measured value is held because ultrasonic

wave cannot be propagated into a pipe.

1. Incomplete installation

• Piping specifications are wrong.

• Sensor is mounted at the welded

part.

• Sensor mounting dimension is wrong.

• Grease application at sensor mounting is incomplete.

• Sensor connector is not connected completely.

• Pipe surface is contaminated.

Remedy

Connect correctly.

Shift measurement location to the site where 10D and 5D can be secured on the upstream and downstream sides.

Mount the instrument with a clearance of 30D or more.

Extend response time through damping setting.

After check, separate the sensor once. Apply the grease again and remount the sensor with a slight shift.

11- 2

2. Problem on pipe or fluid

• When V method is used, it should be changed to Z method.

• When sensor extension cable is used, it should be avoided.

• If error persists, check and eliminate the true cause as instructed below.

Fluid is not filled.

Find the location on the same pipe line, where fluid is filled up and move the sensors to that location. Mount the sensors at the lowest location on pipe line.

State Cause Remedy

BULLETIN F-68

Air bubbles have entered.

In case measurement is normal with water flow stopped, entrance of air bubbles is the cause of this error.

When the sensor is mounted just after a valve, cavitation will occur to cause the same effect as entrance of air bubbles.

Turbidity is high.

Turbidity is higher than those of sewage and return sludge.

Because of an old pipe, scale has

stuck to the inside.

Lining is thick.

Because of mortar lining or the like, thickness is a few ten mm or more.

Eliminate entrance of air bubbles.

• Raise the level of pump well.

• Confirm the shaft seal of

pump.

• Retighten the flange of negative pressure piping.

• Prevent fluid from rushing into pump well.

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

• To the inlet side of pump

• To the upstream side of

valve

• Change the sensor mounting method from V to Z.

• Move the sensor to the location on the same line, where the outer diameter of pipe is smaller.

• Move to a different place or different pipe.

• Raise the voltage for transmission (refer to p.6-12).

Lining is peeled.

There is a gap between lining and piping.

Sensor is mounted at a bent pipe

or tapered pipe.

3. Influence by external noise

• There is a radio broadcasting station in the vicinity.

• Measurement has been conducted near heavy traffic.

• Sensor mounting is incomplete.

• Mounting dimension is

improper.

• Sensor is not in contact with pipe.

4. Hardware error

Try measurement with the optional large size sensor.

Contact

Mount to a straight pipe.

• Minimize the cable between main unit and sensors.

Mount the sensors in parallel with the pipe following the correct mounting dimension. Bring the sensor in close contact with the pipe.

Contact

Dwyer Instruments

11 - 3

State

BULLETIN F-68

Cause Remedy

Measured value is not zero though water flow has stopped.

Measured value has an error.

• Water is subjected to convection in a pipe.

• Zero adjustment has been performed.

• When water flow stops, pipe is not filled up with water or becomes empty.

• Input piping specifications are different from actual ones.

• Because of an old pipe, scale has stuck.

The length of straight pipe portion

is inadequate. 10D and 5D are required at least

on the upstream and downstream sides. Flow disturbing element should not be present within 30D on upstream side. Pump, valve, flow joining pipe or the like is unallowable.

Normal

• Perform zero adjustment again after making sure water flow has stopped completely.

• The measured value, just when ultrasonic wave cannot be propagated, is held.

Normal

• A difference of 1% in inner diameter causes an error of about 3%.

• Input specifications correctly.

• Input scale as lining.

Select a different location of sensor mounting (move the upstream side of a flow disturbing element).

• Mount the sensor at different angles with respect to the cross section of pipe to find the location where mean value is obtainable. The mount the sensor at that location.

11- 4

• Pipe is not filled with water or mud and sand have precipitated.

Precipitation is more when the cross section of pipe has a smaller area.

Shift the sensor to the vertical portion of pipe.

11.4 Error in analog output

BULLETIN F-68

State

Output remains at 4mA though indication value is other than 0.

Output is 0mA. Output is not 4mA

when indication value is 0.

Output rises beyond 20mA.

Analog output remains the same despite change in indication value.

Indication value does not match analog output.

Output remains the same even after calibration of analog output.

Cause

Analog span setting has not been

made.

Cable is broken. The zero point of analog output is not

adjusted properly.

Indication value is larger than analog

span value.

Span is deviated.

Output load is larger than 1kΩ.

• Zero point and span of analog output are deviated.

• Hardware error

Remedy

Set the span. Otherwise, output remains at 4mA.

Repair Calibrate analog output.

Overshoot Set analog span again. Calibrate analog output.

Permissible load is 1kΩ. Reduce the load to less than 1kΩ.

Calibrate analog output.

11.5 Display of error

State

"BACKUP BATTERY FAIL" is displayed on measurement panel.

"INSIDE COMMUNICATION FAIL" is displayed on the measurement panel.

Memory data are all cleared.

• Hardware error

Cause

Remedy

Select the error check item "BACKUP BATTERY FAIL" using the system check page to display the data of processing the error, and then perform the following operation on the measurement panel.

• When "BACKUP BATTERY FAIL" is released, set measurement conditions.

• When "BACKUP BATTERY FAIL" is not released, the memory backup battery needs to be replaced.
