Field hydrostatic pressure testing procedures

The Daniel 3812 Liquid Ultrasonic Flow Meter can be hydro-tested without any special
preparations. The transducers are not exposed to the process pressure and can remain installed
in the meter.
The liquid ultrasonic meter pressure containing parts include but are not limited to the
transducer housings. These pressure containing parts are pressure tested attached to the meter
body as a completed ultrasonic meter assembly. The hydrostatic test is verification of the
pressure containing capability of the liquid ultrasonic meter, pressure containing parts and the
seals that seal them.
LEAKAGE OR PRESSURE CONTAINING PARTS FAILURE
Use precautions to eliminate hazards to personnel in the event of leakage or failure of
the liquid ultrasonic meter pressure containing parts or failure of the test equipment
and to prevent over-pressurization during the test procedure.
Failure to do so may result in injury to personnel or cause damage to the equipment.
