POINTS TO BE CHECKED BEFORE MODEL

SELECTION

It may be unable to make measurement when falling into the

following conditions.

Contact us in advance. When it cannot be judged whether it is

suitable, we are prepared to make preliminary test by the actual

equipment.

1) Liquid

• The liquid containing a lot of bubbles (over 2% only as a

guide).

• The liquid containing slurry and solid material (over 5Vol.%

only as a guide).

• The liquid of low Reynolds number (less than Re.10000 only

as a guide).

• Liquids other than water such as lean chemical solutions,

oils, waste waters and hot spring water.

• Liquids which attenuate Ultrasonic waves

(Typical example:acetic acid)

*This flowmeter cannot be used for High concentration acetic

acid aqueous solution (above 50%) .

2) Piping

• The inside wall of carbon steel pipe is rusty.

• Adhesion and sediment are in a pipe.

• The outside surface of cast iron pipe is coarse.

• Pipe made of PVDF with thickness more than 9mm.

• Pipe made of PP with thickness more than 15mm.

• SGPW pipe [The galvanized steel pipe for water service (white

gas pipe)]

• Lined pipe

3) Straight runs

The accurate flow measurement requires straight runs both

upstream and downstream of the flow sensor as shown at the

next page.

PRECAUTION FOR USE

1) Pipe shall be always filled with fluid.

2) In the case of horizontal piping, please do not mount a sensor

on the upper and the lower part of piping.

3) When you wrap a sensor in an insulating material, be careful

not to exceed the ambient temperature limits of a sensor.

4) In order to prevent the sensor grease from degrading when

installed outside, we recommend you to mount the waterproof

cover which covers a sensor assembly.
