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°
