Do not touch the terminal board when
power is supplied.
Touching the terminal board
when power is supplied can
cause electric shock.
Follow the procedure described below to prepare before starting the flow measurement (described with
regard to the entire flowmeter).
Check the wiring between the converter and related instruments.
Make sure all the bolts of connection flanges on which the flowmeter is mounted securely
Make sure the direction of flow arrow is in accordance with actual flow.
Make sure the flowmeter is grounded with 100 ohm or less ground resistance.
Make sure the housing covers are securely tightened.
Placing System On-Stream
Let the fluid go through the detector pipe. (Note 1)
When the detector is filled with the fluid, stop the fluid and keep it still in the detector pipe.
Supplying Electric Power
Make sure the power supply is as specified.
Checking Converter Parameters
Check the configuration parameter settings. Refer to combined converter's manual.
Wait for 30 minutes to warm up the flowmeter. Then making sure the fluid holds still in the
detector pipe, starts the zero adjustment. Refer to combined converter's manual.
After checking the items and conducting the zero adjustment as listed above, let the fluid go
through the detector pipe. Output (4–20 mA dc) directly proportional to the flow rate can be
Note 1: If the detector pipe is not filled with the fluid to be measured, the flow rate will be
indefinite and unable to be measured. Before using the flowmeter , be sure to fill the
detector pipe the fluid to be measured.
Check the items listed below

Do not touch the main body when high
temperature fluid is being measured.
The fluid raises the main body
temperature and can cause burns.
