Ultrasonic Open Channel Ultrasonic Flow Meters / Ultrasonic Water Meter For Sewage Treatment Plant STP 200m3/H

Ultrasonic open channel flow meters non contact sensor for sewage treatment plant STP 200m3/h

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.

Main technical index

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
