IP68 Velocity 12m/S Insertion Type 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.
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 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. Straight Pipe Demand
We suggest avoiding the valve, T-branch pipe and elbows if the
condition allow.
Please satisfied the hardest position installation requirements
when you face more than one interfering resource.
V. 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.
