Waterproof Transit Time DN1200 External Pipe Flow Meter
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
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.

V. Installation Site Selection
The first condition for ultrasonic flow meter is the pipe must be full of liquid, the bubbles will greatly influence the accuracy of the measurement, please avoid the follow installation position.
The suggestion installation area is as following:
A is for upright pipeline, please notice the water direction is from the bottom to top.
B is for horizontal pipeline, the transducers need to be installed inside the C area,angle for area C, max 120°
