China Clamp On Ultrasonic Flow Meter With Data Logger Velocity 0.03m/S~12m/S
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.
ML-6100S can be used in conjunction with the RTD module and the PT1000 temperature sensor to become an energy meter for measuring the heat and cold consumption of heating pipelines and air-conditioning refrigeration pipelines;
The PT1000 uses high-temperature resistance lines, imported movements,and its sensitivity and working conditions durability are much higher than those of domestic PT100.
II. Working Principle
The external clamp or pipe segment ultrasonic flow meter is a meter that measures the liquid flow in the round tube according to the principle of "speed difference". It uses advanced multi-pulse technology, signal digital processing technology and error correction technology, so that the flow meter can be more adapted to the industrial field environment, measurement is more convenient, economical and accurate. Products reached the advanced level at home and abroad, can be widely used in petroleum, chemical, metallurgy, electricity, water supply and drainage and other fields.
