Back Lit LCD Display RS232 RS485 Fixed Ultrasonic 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.
- External clamping flow meter sensor, simple and convenient
installation, high flexibility
- Integrated design and manufacturing, the true meaning of IP68
waterproof
- Hidden pipe design, more beautiful after installation
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 clamp-on or tube-segment ultrasonic flow meter is a meter that
measures the flow of liquid in a round tube based on the principle
of the "speed difference method". It uses advanced multi-pulse
technology, signal digital processing technology and error
correction technology to make the flow meter more adaptable to the
environment of the industrial site, 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, metallurgy, electric power, water supply and
drainage fields.
