9.1 STANDARD SPECIFICATION
Fluid to be Measured:Liquid
Measuring condition: Sound speed 500 to 2000 m/s
Be sure there are no bubbles in the flow.
Avoid severe sticky and slurry fluid meterings.
Do not use this meter where pulsating flow/pulsating pressure
exist.
Measurable Flow Rates: Refer to item 6.1.
Accuracy: ± 1.0% of reading
± 0.5% of reading is also available as an option.
(refer to item 6.1)
Note: The above shows the accuracy of pulse output. For analog
output, add up ± 0.1% of full scale to the above values.
Repeatability: ± 0.2% of reading
Process Temperature Range: –40 to 200 °C (–40 to 150 °C for 15A)
Process Pressure Limit: Up to flange rating.
Ambient Temperature Range:
