For Monitoring Water Level and Open Channel Flow
|
|
|
The
WL700 uses the latest ultrasonic distance measuring technology for accurate
non-contact
|
|
|
water level monitoring. The fully encapsulated sensor/
transmitter is temperature compensate
|
|
|
and provides an industry standard 4-20 MA
output. There are three ranges available including
|
|
|
1’,
3’ and 6’ to meet a wide variety of applications. The unique
1’ range sensor is ideal for
|
|
|
measuring flow in small flumes and weirs. The 3’ and
6’ ranges are best for measuring river, lake
|
|
|
and tank levels and for measuring open channel flow in
larger flumes. Installation is simple and
|
|
|
requires no programming or calibration. No maintenance is
required.
|
|
|
The WL700 Ultrasonic Level Sensor is rugged, reliable and
completely weatherproof. It is ideal for
|
|
|
sewer or wastewater applications. The
sensor is easy to mount, comes with a 10’ cable and
|
|
|
complete instructions. It is
easy to interface to all PLC’s, SCADA and
telemetry systems with its
|
|
|
simple 3-wire 4-20 MA output. The WL700 is
compatible and provided optionally with the Global
|
|
|
Water FC200 Open Channel Flow Monitor and the PC300 Process Controller
(for water level control).
