36VDC Hot Tap Ultrasonic Insertion Water Flow Meter

Hot Tap Ultrasnic Insertion Water Flow Meter Sensor

I. Introduction

ML-6100S is a wall-mount, clamp- on type ultrasonic flow meter which uses the transit-time technology. Designed using FPGA chip and low-voltage broadband pulse transmission.Both clamp on type sensors and insertion type sensors are available.

ML-6100S has a 240*128 back lit LCD with 4 line menu display and also the clear,user-friendly menu selections make flow meter more simple and convenient to use.Daily, monthly yearly totalizer. Parallel operation of positive, negative and net flow totalizer with scale factor (span) and BTUcapacity. While the output of totalizer pulse and frequency output are transmitted via relay and open collector.

II.Working Principle

The external clamp type or pipe segment ultrasonic flow meter is an instrument for measuring liquid flow in a circular tube based on the principle of "velocity difference method".

It adopts advanced multi-pulse technology, signal digital processing technology and error correction technology, so that the flow meter can better adapt to the environment of the industrial field, and the measurement is more convenient, economical and accurate.

The products have reached the advanced level at home and abroad, and can be widely used in petroleum, chemical industry, metallurgy, electric power, water supply and drainage and other fields.

IV. Measuring Principle

Transit-time technical means the ultrasonic signal from the transducer is transmitted and received through the moving liquid, there will be a difference between the upstream and downstream transit time, which can be used to calculate flow and velocity.
