Redundant vortex flowmeter

The redundant mode vortex flowmeter is an optional product of the YYW-ZF series. It refers to the utility model patent of a "diaphragm type vortex flowmeter with a dual measurement mode" and is installed at the same time above the surface of the membrane type sensor. After passing the factory inspection, the majority of vortex converters measure the flow signal at the same point and are used for vortex flowmeters with different control, output and detection requirements.

Product introduction

The redundant mode vortex flowmeter is an optional product of the YYW-ZF series. It refers to the utility model patent of a "diaphragm type vortex flowmeter with a dual measurement mode" and is installed at the same time above the surface of the membrane type sensor. After passing the factory inspection, the majority of vortex converters measure the flow signal at the same point and are used for vortex flowmeters with different control, output and detection requirements.

Product parameters

Without changing any structure and size of the measurement body, realize the same monitoring point and dual signal acquisition function

The multi-directional valve structure adopts an integrated design without any leakage points, and the two signal acquisition channels do not interfere with each other

There is no obstruction in the vortex signal channel of the multi-directional valve. The two-way signal measurement has the same effect as without the redundant valve.

The deviation of the two signals is ± 2.0%. Single channel accuracy meets ± 1.0%

Application Industry

YYW redundant vortex flowmeter is widely used in petroleum, chemical, pharmaceutical, metallurgy, food, scientific research units, etc.
