The new WELL WATCHER (TM) hydrostatic level gauging system
from AMETEK Drexelbrook was developed to be an easy-to-use, high-accuracy
liquid level measurement system designed for a wide range of applications from
basic well level measurement to sophisticated process tank level control.
The system is a cost effective alternative to other
electronic devices, such as capacitance sensors, conductivity probes,
ultrasonic or radar devices which can be cost prohibitive and limited to a more
narrow range applications.
Unlike mechanical systems, such as floats and bubblers that
can require extensive maintenance, the WELL WATCHER is designed to offer simple
installation and requires little or no maintenance. In addition, no calibration
The system consists of a rugged stainless steel submersible
transmitter and a fully calibrated microprocessor-controlled digital meter. It
can be factory calibrated for inches, feet or meters of water or any desired
engineering units. Combined in a compact NEMA 4X meter housing, it is designed
to be a versatile, level measurement system.
The piezoresistive technology of the electronic transmitter
indicates liquid level by continuously measuring hydrostatic pressure through
its nose-mounted sensing element.
Accuracy of the
WELL WATCHER is ±0.25 percent of full scale including linearity,
hysteresis, and repeatability. The device operates in depths from 6 feet to 690
feet (210 meters) at pressures up to 300 psi.
The system uses a stainless steel transmitter. A series of
perforations in the bottom of the unit protects the sensing port from either
clogging or damage. The same snub-nosed end can also unscrew, allowing for easy
After the transmitter is lowered into a well, tank or
reservoir, the system hydrostatically measures the level of liquid. The meter
then displays the level data, and if required, transmits the level data to
another receiver for remote monitoring, recording and control. Two relays are
provided for pump control or to activate alarms.
The customized meter displays data from the transmitter,
provides excitation voltage, and transmits an analog signal for remote
recording, alarm, or control functions. Its dual-programmable set points permit
high-high, low-low, or high-low control with adjustable hysteresis.
The large four-digit LED display gives local indication,
while the optional isolated analog output can interface with ancillary display,
recording, or control devices. Two relays are provided for pump control or to
