Clamp On Ultrasonic Flow Meter / Heat Meter Manufacturer
I. Introduction
ML-6100S is a wall-mounted clamping ultrasonic flowmeter, which adopts time difference technology. The transmission is designed with FPGA chip and low voltage broadband pulse. Two can provide clamping sensors and plug-in sensors. The ML-6100S has a 240*128 backlit LCD with four lines of menu display, and the clear and user-friendly menu selection makes the flowmeter more simple and convenient to use every day. Parallel operation of positive, negative and net flow totalizers with scale factor (span) and BTU capacity. The pulse output and frequency output of accumulator are transmitted through relay and open collector.
ML-6100S can be used together with RTD module and PT1000 temperature sensor, and become an electric energy meter for measuring heat consumption and cold consumption of heat supply pipeline and air conditioning refrigeration pipeline; PT1000 adopts high temperature resistance wire and imported movement, and its sensitivity and working environment durability are much higher than those of domestic PT100.

IV. Working Principle
External clamp type or pipe section type ultrasonic flow meter is an instrument that measures liquid flow in a circular pipe 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 more adapt to the environment of the industrial site, measurement more convenient, economical and accurate. The products reach 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.
