Water Flow Rate Meter

Water Flow Rate Meter

Introduction FT 201 is a wall-mount, clamp- on type ultrasonic flow meter which uses the transfer time technology. Clamp on type ultrasonic flow meter is easy to install and no need to cut off the pipe that saves you lots of troubles and cost. At the same time FT201 has our unique calculate software to ensure the high accuracy and low velocity response. FT201 ultrasonic flow meter widely application in oil industry, water treatment, pure water, chemical and etc. FT201 could add the RTD model and temperature sensor become an energy meter to monitoring the energy use, help to save the energy.

Features of FT201

 

Comparing With other traditional flow meter or ultrasonic flow meter, it has distinctive features such as high precision, high reliability, high capability and low cost, the Flow meter features other advantages:

1. With ARM COMA chip, low power consumption, high reliability, anti-jamming and outstanding benefits.

2. User-friendly menu designed. Parameters of pipe range, pipe material, pipe wall thickness, output signals, etc can be conveniently entered via the windows. British and Metric measurement units are available.

3. Daily, monthly and yearly totalized flow: Totalized flow for the last 64 days and months as well as for the  last 6 years are may be viewed. With the SD Card, 512 files can be stored; the time interval can be within 1 second.

4. Parallel operation of positive, negative and net flow totalizer with scale factor and 7 digit display. Internally configured batch controller makes batch control convenient.

The flow meter ensures the higher resolution and wider measuring range by the 0.04ns high resolution, high linearity and high stability time measuring circuit and 32 bits digits processing program.

      Theory of Operation

 

When the ultrasonic signal is transmitted through the flowing liquid, there will be a difference between the upstream and downstream transit time ( travel time or time of flight ), which is proportional to flow velocity, according to the formula below.
