FSH Hybrid Ultrasonic Flowmeter The new generation of hybrid ultrasonic flowmeter (non-contact measurement) that uses the new pulse Doppler method and the propagation time difference method can automatically switch to measure according to the fluid state.
Features：
The automatic switching between the pulse Doppler method using ultrasonic reflection characteristics and the propagation time difference method using ultrasonic penetration characteristics can be applied to a wide variety of liquids, regardless of whether or not air bubbles or particles are mixed.
The volume flow rate of the liquid flowing through the piping is measured with high accuracy of 0.5% to 1%.
When the pulse Doppler method is used for measurement, the distribution of the flow velocity can be displayed in real time through the computer (optional).
High-speed response: 0.2 seconds/pulse Doppler method
0.5 sec/propagation time difference method
Adopts a clamp-type detector that does not require piping construction
Also suitable for double measuring lines
