Product Introduction


Handheld Ultrasonic Flow meter can be applied to a wide range of pipe flow measurements.

Applicable liquids include pure liquids as well as liquid with small quantity of tiny particles.

Such as Water (hot water, chilled water, city water, sea water, waste water, etc.)

Sewage with small particle content;Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.);

Chemicals (alcohol, acids, etc.);Plant effluent;Beverage, liquid food;Ultra-pure liquids;

Solvents and other liquid.

 Handheld ultrasonic flow  sensor meter clamp-on sensors to measure liquid flow. Installation process is very simple, all Chinese human-machine interface, more easy to operate. Particularly suitable flow balance testing and flow monitoring: drinking water, river water, sea water, cooling water, hot water, industrial waste water, lubricating oil, diesel oil, fuel oil, chemical liquids.  

   The principle of Handheld ultrasonic flow  meter :

   1) Time difference measuring principle: a probe transmission signal after passing through the wall, the media, the other side of the wall, another probe is received, while the second probe, also launched a probe signal is first received, due to the media the impact velocity, there is a time difference Δt between the two, according to projections can be drawn in terms of the relationship between flow velocity V, and the time difference Δt between V = (C2 / 2L) × Δt, in turn, can obtain flow values.
   2) Measuring principle: difference correlation principle flow rate: 0.01 ~ 25 m / s Resolution: 0.025 cm / s Repeatability: 0.15% of reading, depending on the application accuracy :( fully developed flow field and radially symmetric) Volume flow: ± 1% reading, depending on the application ± 0.5% of reading, calibrated flow rate: ± 0.5% of reading, depending on the application can be measured media: all acoustically conductive fluid, and the volume content of bubbles or solid particles of <10%
