TDS-100H Portable Flow Meters

 

The TDS-100H ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit.  The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. The TDS-100H transit time flow meter utilizes two  transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.  The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in 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 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

 

TDS series Handhold Ultrasonic 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 for 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.TDS-100H handheld ultrasonic flow meter is a battery-powered ultrasonic flow meter with the capability of a full-size flow meter. It is carefully designed for portability and ease of use.
