with Two Non-Contacting Ultrasonic Sensors

Install one Sensor on each side of a barscreen to continuously monitor,
transmit and control level. Use the built-in control relays or 4-20mA
outputs to automatically activate the barscreen rake at preset levels.

The DLT 2.0 is a simple solution for barscreen level control at wastewater
treatment plant headworks, pump stations and combined sewer systems.
It includes two non-contacting ultrasonic sensors to measure level. With
sensors positioned above a channel, up and downstream from the
barscreen, the DLT 2.0 can display and transmit differential level. The
downstream sensor can also be installed above a flume or weir to
measure and totalize open channel flow.

Three 4-20mA outputs are configured to transmit upstream level,
downstream level (or flow) and differential level. Built-in relays can be
calibrated for level control, differential level control or open channel flow.

Barscreen Differential

Open Channel Flowplus

Reduce costs and simplify instrumentation at
treatment plant headworks. With a barscreen
upstream from a flume, the DLT2.0 can measure
both

differential level and flow through the flume
with just two ultrasonic sensors and one electronics
enclosure.

The DLT 2.0 includes three 4-20mA outputs. It
displays flow rate and total flow through the flume,
plus upstream level and differential level.

Barscreen Differential

Monitor, transmit and control barscreen level with
one instrument. Ultrasonic sensors mount up and
downstream from a barscreen. Use the isolated
4-20mA outputs or control relays to activate the
screen’s cleaning rake at preset levels or differential
level.

4-20mA Tank 1 - Level/Volume

4-20mA Tank 2 - Level/Volume

Two-Tank Inventory

Monitor level in two tanks with one instrument. The
DLT 2.0 will alternate display of level in both tanks
plus transmit 4-20mA outputs. Use the built-in
relays to activate alarms or level controls.

Calibration is easy with the DLT’s built-in keypad
and menu system.

Submerged Flow Alarm

Parshall flumes can provide accurate flow
measurement with the discharge submerged up to
70% (depending on flume size). Use the DLT 2.0 to
measure flow through the flume and to activate an
alarm when discharge level reaches critical
submergence level.
