Sampling
Pump & Transducer

Dedicated pressure transducers allow rapid and accurate measurement of temperature and total water pressure. Unless static water levels are shallow, transducers are the preferred method of water level measurement, both from an efficiency and an accuracy point of view.

The transducers commonly chosen for use in the Waterloo System are unvented vibrating wire transducers, which are very accurate and rugged. They have superior long term operation with minimal drift over time. They can be read with a manual readout, or with a datalogger which can provide remote, unattended monitoring and telemetry, if desired. Transducers are available with pressure ranges from 50 psi to 435 psi. (350 kPa to 3 MPa).

 

Discrete Zone Water Level Monitoring

Water level measurements can be made in Waterloo ports fitted with an open tube using the narrow, Model 102 Coaxial Cable Water Level Meter. It has a P4 probe, 0.157" OD by 1.5" long (4 mm x 38 mm).

Sampling may be performed in open tubes using a Mini Inertial Pump, Micro Double Valve Pump, or a Peristaltic Pump.
