PCE-TDS 100H/HS Ultrasonic Flow Meter
Ultrasonic flow meter according to the differential measurement of duration method /
determines flow velocity and flow / measuring method for homogeneous liquids / 
with sensors for different pipe sizes

PCE-TDS 100H/HS ultrasonic flow meter  is designed to measure the fluid velocity of liquid within a closed pipe. It is a hand-held measurement system which is both easy to use and to install. The PCE-TDS 100H/HS ultrasonic flow meter operates according to the difference in the transit time measured. The measuring principle of the PCE-TDS 100H/HS ultrasonic flow meter is very easy. 

In a diagonal measurement the tube will need less time in the same flow direction than against the flow direction. When the flow increases, it will need more time to measure flow if the measurement is against the flow direction and less time if the measurement is in the same flow direction. The difference between the flow direction therefore directly depends on the flow velocity. The PCE-TDS 100H/HS ultrasonic flow meter determines the flow velocity. Electro acoustic transducers receive and emit brief ultrasonic pulses through the liquid of the pipe. Transducers are vertically placed on both sides of the measured pipe. Sensors are placed on the pipe and fastened by means of a flange. The display will quickly show the flow velocity. The PCE-TDS 100H/HS can be used for metallic, plastic and rubber tubes.

Additional accessories for the ultrasonic flow meter

The calculation of the flow velocity according to the in transit time measured follows the equation below:

v -measured velocity
T1 - Run time of the ultrasonic sign in the flow direction
T2 - Run time of the ultrasonic sign against the flow direction
 L - length of the ultrasonic way
α - ultrasonic signal angle to the flow
