Flowmasonic WUF100J Portable Flow Meter

Product Specification Flowmasonic WUF100J Portable Flow Meter

The WUF100J transit time portable flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. To install the sensor is to clamp the transducer on the outer surface of the pipe with a specified distance. The transducers ultrasonic can be mounted in V-method where the sound transverses the pipe twice. The Other method is  Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.

This selection of the mounting method depends on a pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, show as follow s:

Type of Transducer Installation

This selection of the mounting method depends on a pipe and characteristic of liquids.  The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers.

Flowmasonic WUF100J Flow Meters are based on clamp-on transit-time flow measurement principle. It measures the flow rate of liquid in a pipe from outside of the pipe by using a pair of ultrasonic transducers.

In general, the liquid should be full in the pipe and should contain very little particles or bubbles. It is applicable to water (hot water, chill water, city water, sea water, etc.); sewage; oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.); chemicals (alcohol, acids, etc.); waste; beverage and liquid food, solvents and other liquids.

The WUF-100J handheld ultrasonic flow meter is a battery-powered ultrasonic flow meter with full-size flow meter capabilities. The design is very perfect where the way to operate it is easy and can be done anywhere
