Integration Open Channel Flow Meter , 85 265V AC Ultrasonic Flow Meter

integrated open channel flow meter, ultrasonic flow and level meter for ETP 9000m3/h

Work principle
Ultrasonic transducer, is a transceiver which emits high frequency sound, which hits the medium surface and returns back to the sensor receiver. The time of travel of the ultrasound is inversely proportional to the height of the flowing medium. This way the height of the flowing medium is calculated. And with the algorithms programmed the Height, Flowrate and Total Flow are calculated and displayed.

General 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.

Main technical index

Dimensions

Features

• Built-in variety of algorithms, suitable for a variety of standard weirs.
• Stable sensors - Suitable for harsh industrial situations
• Isolated 4~20mA current output. Optional spot bus interface.
• The blind zone can be manually set, shielding the probe near the interference signal.
• Calibrated at Factory. And if required we shall do calibration at site.

Sensors

Ultrasonic sensor Static pressure sensor
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.

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.
