Instrument Overview

Widely used for online measurement and system monitoring of nearly all liquids in applications such as pipelines, petrochemicals, metallurgy, power generation, water conservancy, municipal water supply companies, and energy monitoring. It enables the measurement and detection of instantaneous flow rates and positive and negative cumulative volumes for various types of fluids, as well as functions such as flow switches and fluid identification.

Product Features

(1) High cost-effectiveness, can be installed without interrupting water supply, and does not affect production.

(2) It features long-term stable and reliable operation, as well as convenient online maintenance.

Technical Parameters

Measurement principle	Principle of the Ultrasonic Time-Difference Method
Flow rate range	0 ~ ±12 m/s
Measurement caliber range	DN80 – DN6000
Accuracy	Better than ±1.0%
Host protection level	IP67
Sensor protection rating	IP68 (encapsulated)
Power supply	DC 8–36V or AC 220V
Host operating temperature	-20℃ to 60℃
Sensor operating temperature	-30℃ - 160℃
Communication interface	Equipped with a 485 communication interface, a 4–20 mA current signal, and pulse signal output.
Sensor structure	The probe’s lead screw features a depth-adjustment scale; the sensor’s lead screw has no threaded seal, allowing it to be inserted vertically without the emission angle being affected by the thread.
Communication protocol	Supports MODBUS-RTU protocol and supports various manufacturer-specific protocols.
Signal input	3-channel 4–20mA input, with an accuracy of 0.1%. It can accept current signals from various sources such as pressure, level, and temperature—options include 4–20mA or 0mA–20mA. The impedance is floating from 0 to 1kΩ, with an accuracy of 0.1%. Supports both active and passive output modes.
Output pulse signal	Positive, negative, and net flow rates, as well as cumulative heat pulses, with one relay output and one OCT output; pulse width: 6–1000 ms.
Output an alarm signal	Up to nearly 20 different alarm states are available, with alarms output via buzzer, OCT interface, and relay interface.
Supports installation with water.	For pipelines that cannot be welded, you can opt to install custom pipe clamps with pre-welded bases, complete with hole-cutting tools.
Other parameters	The dot-matrix backlit LCD display simultaneously shows cumulative flow, instantaneous flow, and instrument operating status. The instrument comes with nine built-in status indicators that allow you to directly identify the cause of any instrument malfunction. Automatically memorizes the cumulative flow for the past 512 days, 128 months, and 10 years. Automatically records call-in and power-off times, as well as instrument failure operating hours, and features a power-off flow compensation function.
