High Quality Transit Time Ultrasonic Flow Meter
I. Introduction
The ML-6100S is a wall-mounted clamped ultrasonic flow meter with
jet lag technology. The transmission is designed with FPGA chips
and low voltage broadband pulses. Two are available for clamping
sensors and plug-in sensors. The ML-6100S has a 240 x 128 backlight
LCD, 4-line menu display, and clear, user-friendly menu selection
makes flow meters simpler and easier to use every day, month-year
accrualer. The positive, negative, and net flow accumulators run in
union and have scale factor (span) and BTU capacity. The loader
pulse output and frequency output are transmitted through relays
and collectors.
ML-6100S can be used with RTD module and PT1000 temperature sensor
to become a watt-hour meter for measuring heat and cooling
consumption of heating pipes and air-conditioning refrigeration
pipelines. PT1000 adopts high temperature resistance line and
imported movement, its sensitivity and working environment
durability are much higher than those of domestic PT100.
II. Working Principle
The external clamp type or pipe section type ultrasonic flow meter
is based on the principle of "velocity difference method" to
measure the liquid flow in the pipe. It adopts advanced multi pulse
technology, digital signal processing technology and error
correction technology, so that the flow meter can adapt to the
environment of 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 the
fields of petroleum, chemical industry, metallurgy, electric power,
water supply and drainage, etc.
