Mounting The Sensor
(Mounting hardware not included with sensor)
3. Tubing Connections
CAUTION: DO NOT FLOW ANY LIQUID THROUGH A GAS
FLOW SENSOR OR FLOW METER. THIS WILL SERIOUSLY
AFFECT THE PERFORMANCE AND VOID THE WARRANTY.
CAUTION: DO NOT FLOW A HIGH PRESSURE GAS
THROUGH THE SENSOR. A burst of high pressure gas may
cause the unit to be damaged. Always flow gas at a pressure and
flow rate within the specifications of the unit.
All tubing must be clean, dry and without crimps, burrs or scratches.
Only use the factory installed fittings on the unit. If the fittings are removed
the calibration of the unit may be effected and leaking may occur. If
different fittings are required please contact the Dwyer Instruments Service
Department for assistance.
When connecting the sensor to the tubing a wrench should be used to stop
the fitting rotating in the sensor body. Take care not to over tighten the
fittings or leaking may occur.
