Product Details
Open channel flow meter for effluent flow monitor, parshal flume,
level transmitter
Product introduction
The Open channel Ultrasonic Flowmeter is a high precision flow
measurement instrument, which use Transit Time Ultrasound principle
to measure the flow in a variety of Flumes, Weirs or Troughs.
Features
- With a fully independent intellectual property rights.
- Has wide range of temperature compensation and original ERD
interference intelligent identification system, measurement data
stability, high precision.
- Six groups flow condition all data sending 485 serial ports output,
PC directly receive, decimal shows, the convenient user record and
read archived.
- Original "fluid flow correction system" that flow coefficient
according to slot size and level to be automatic operation weir and
timing compensation.
- The blackout time time, the year/month/day/when/points/SEC, flow
data, using the ferroelectric double backup storage 10 years off.
- Original "measuring tank jam recognition alarm system" can detect
liquid slag quality measurement slot throat and obstruction caused
by measurement.
- Precise date determined when the calendar clock Settings, display
and cooperate with the memo and time axis to file information
records.
- Has 4~20 mA three wire system, RS485, switch quantity and so on
many kinds of signal output function selection.
- Using intelligent measuring high, digital calibration, the user
installation calibration simple and quick.
- The ultrasonic non-contact measurement with no moving parts, flow
without components within, no block sensor fault hidden trouble.

Applications
Measurement of water flow in Effluent, Waste Water, Rivers, Canals,
Drains, Sewage, etc.
Flow Totalizer parameters
Flow measuring range: Depends on the size of the flume.
Maximum Count: 9999999999
Types of suitable weirs: Triangular weir, rectangular weir,
Parshall flume, etc.
Display accuracy: 1 count. Overall accuracy depends on the input
signal. Different Weirs /
flumes has different accuracies. A triangular weir has 1 to 2% flow
error, a rectangular weir
has 1 to 4% accuracy, a Parshall flume has 3% flow error, etc.
Display: 2.8-inch LCD. Displays Height, Flowrate, Total Flow, etc.
Output
Voltage output: DC 12V or 24V
Signal output: RS485/RS232; 4~20mA; 2 channel relay
Troughs
Triangle weirs
Installation sample
Advantage
The production capacity is 20000 ultrasonic converter and 100,000
ultrasonic sensor.
Company Profile
Shanghai I Fluid Technology Co., Ltd, a technique based company. We
focus on the deployment , installation and management system of
smart metering and smart grid in all utility sectors, include but
not limited to water, heat, gas and electricity.
To adapt to the global environment protection trends, and China
government policy, China put the green energy application and EIA
at their first place. We do our best contribution to the government
energy saving policy.
We put emphasis on central air conditioning system, energy
distribution system in separated areas, green energy application in
commercial buildings, municipal water / gas / heat supply, sewage
discharge monitoring, and many other industrial applications.
Adhere to the principle of “ low carbon energy, build future”, we
aim to give solution to take the best avail of natural resources,
improve energy efficiency, reduce energy consumption. Through more
renewable energy, reasonable energy store technique, and minimize
energy demands, we help our clients to build an intelligent low
carbon energy network. Build the optimized electricity, heat, water
and gas supply and demands system, finally to realize the LOW to
ZERO energy system.
Over tens of years developing, we design and manufacture a complete
set of energy relating products: central air condition with
variable ventilation and ventilate at low temperature, flexible
central air conditioning, cooling store capacitor, AMR/AMI,
metering and level products.
