Adjustment and Operation
Connect load before turning on the power.
Supply the power when there is no flow.
If using the product to detect very small flow rates, warm up the product for 10 to 15 minutes first. There
will be a drift on the analogue output of approximate 2 to 3% immediately after the power supply is turn
on, within 10 minutes.
Check regulators and flow adjustment valves before introducing the fluid.
If pressure or flow rate beyond the specified range are applied to the sensor, the sensor unit may be damaged.
Do not attempt to insert or pull the flow rate sensor or its connector when the power is on.
The product is a flow meter using Karman vortex. The flow meter using Karman vortex has lower output
frequency at excess flow state. Do not use the product within the excess flow area in the chart below.
