Group: Ultrasonic Flowmeters
US300PM Ultrasonic Flowmeter (Portable type)
The model US300PM is a portable ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300PM provides fast, accurate, and no-zero offset flow measurements in clean to dirty fluids.
The usage of US300PM is not only for the maintenance and the check of your facilities but also for the measurements at laboratories or manufacturing line. The transducers are made for harsh industrial environment.
Equipped with a rechargeable battery that can operate for up to 14 hours on a single charge. Comes with an AC adapter.
US300FM Ultrasonic Flowmeter (fixed type)
The model US300FM is an ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300FM provides fast, accurate, and no-zero offset flow measurements in clean to dirty fluids.
Comes with transducers in three sizes that accommodate pipe sizes from 25mm to 6500mm
Features: US300 Series Ultrasonic Flowmeters
Measuring principle of transit-time
The transit-time utilizes the propagation time of the ultrasonic signal in the fluid.
A pair of transducers are installed on the outer surface of the pipe as shown in the diagram. Each transducer works alternatively as both transmitter and receiver of ultrasonic signals.
When the ultrasonic signal is transmitted toward the upstream side against the flow direction, more propagation time is required (T1). On the other hand, when it is transmitted toward the downstream side with the flow direction, the propagation time is less (T2). That is, the signal is delayed or speeded up by the moving fluid. The difference in time between "T1" and "T2" is proportional to the flow velocity, and the flow volume can be calculated by multiplying it by the cross-sectional area, which is obtained by using the pipe diameter and wall thickness.
