WP810 Vortex Flow Meter
Summary:
The WP810 series is a vortex-shedding water flow sensor based on the Von Karman vortex shedding principle. Under specific conditions, when a fluid at a given volumetric flow rate passes by a bluff body, alternating rows of counter-rotating vortices with regular spacing are periodically formed on either side of the bluff body, creating a Von Karman vortex street. The sensor uses an internal chip to detect the frequency of these vortex passages and thereby calculates the liquid flow rate in the pipeline. Featuring long service life, resistance to fouling, high accuracy, fast response, and zero drift, this sensor is an ideal choice for demanding yet cost-sensitive OEM applications.

Detailed introduction
Product Features
- The device has no moving parts, ensuring high reliability, easy installation, no need for on-site calibration or testing, and virtually maintenance-free operation.
- The installation method is flexible: depending on the specific process piping at the site, it can be mounted horizontally, vertically, or at various inclined angles.
- It features low pressure loss—approximately 1/4 to 1/2 that of an orifice plate—and is classified as an energy-saving flow meter.
- Wide measurement range and high accuracy; typical liquid measurement accuracy can reach ±1.5%.
- The circuit incorporates multiple protection modes, offering surge immunity and strong field adaptability.
- The flow meter measures pulse frequency, which is linearly proportional to the actual flow rate of the fluid being measured, with no zero-point drift and stable performance.
- High-precision sensor probe featuring a piezoelectric crystal design for stable signal output.
- The output options are versatile, supporting pulse, 4–20 mA, and RS485 interfaces—no custom configuration required.
