Introduction

Principle & Structure

An instrument for measuring volume flow by detecting the action of an ultrasonic beam (or ultrasonic pulse) when the fluid is flowing. The externally attached ultrasonic flowmeter is composed of a host and an externally attached sensor. It only needs to stick the sensor on the surface of the pipe to complete the flow measurement of various liquids. Compared with other types of flowmeters, it does not need to cut off the pipe and the flow is convenient to install.

application

It is widely used in tap water, heating, water conservancy, metallurgy, chemical industry, machinery, energy and other industries, and can be used for production monitoring, water balance debugging, heating network balance debugging, and energy saving monitoring.

Features

● Optimal choice when new large-scale pipelines have no real-flow verification parameters

● Can measure non-conductive liquids

● The measurement of DN15~DN6000mm pipeline can be completed by a set of host and several pairs of sensors

● No flow obstruction measurement, no pipeline pressure loss

● Automatically memorize the accumulated flow for the first 512 days, the first 128 months and the first 10 years, automatically memorize the first 64 times of on-off time and flow rate, and automatically memorizes whether the working state of the flowmeter is normal for the first 32 days

● Supports heat measurement and is connected with a temperature sensor to realize heat measurement.

● Support SD card memory, which can realize data storage.
