With man’s increasing need
to consume water, need to measure water in open channels has also increased.
Open channels are those natural and man-made structures through which water
flows with a free surface. For open channels a number of different and varied
methods have been developed to measure the flow of water. Modern mechanical and
electronic flow meters have made the continuous measurement of open channel
flows possible.
Pune Techtrol offers
solutions for measuring “Loss of Head”
(differential level) between upstream and downstream of the filter
screen in open channels of WTP’s / ETP’s, filtration stations, water management
systems, etc.
Techtrol’s ultrasonic loss
of head level system – LHUS is widely used in water canals, water treatment
plants, sewage pumping and filter stations. It consists of a pair of ultrasonic
transmitters and a differential level controller. The transmitters are
installed on either side of the filter screen to translate the level change
into an analog signal by using time of flight principle. The relative
difference between the two signals from upstream and downstream is processed by
the evaluation unit and displayed as “Loss-of-Head” digitally.
Salient Features
Ultrasonic, Non-contact
measurement.
Easy to install and operate.
Minimal maintenance due to
non-moving parts
Displays differential level
Easy calibration through
keypad
Option of Re transmission
4-20 mA for DCS/PLC
Two potential free
change-over relays can be configured as Single Point or Pump Control/Screen
Control Alarm for either Low Head, High Head or Difference.
System Operation
The system (Fig 1) consists
of two Ultrasonic Transmitters (Ultratrol), which consist of ultrasonic
transducer integral with microcontroller based electronics housed in an
enclosure. Ultrasonic pulses emitted from the transducer to the target are
reflected back and sensed by the electronics to provide 4-20mA current output.
The two Ultrasonic Transmitters are mounted on the upstream and downstream side
of the bar screen placed in an open channel. These transmitters are connected
to Differential Level Controller (TDLC) with relay set at a predefined value.
The level difference between upstream and downstream side is measured by the
TDLC to actuate a preset relay.
TDLC can also be provided
with 4-20mA (re- transmission) to DCS / PLC Screen Panel for further control
and automation.
Applications:
“Techtrol” Loss of head
ultrasonic system-LHUS is suitable for use in Waste Water, Sewage, Effluent
Treatment Plants, Open Channel, and Water filtration plant –filter bed level.
