venturi tube

Classic venturi tube,easy installation, good durability, stable performance,low pressure loss.

1. Introduction:    Venturi tube measuring instrument / tool is often used for measuring the volume flow of stable single-phase fluid(liquid, gas and steam) in closed pipe. It is manufactured according to International Standard ISO5167 and Chinese National Standard GB/T2624. Of all throttling devices, classic venturi tube has the lowest requirement of upstream and downstream straight pipe and the lowest pressure loss, also features like stable performance and easy maintenance.

2. Features:a) Easy installation, good durability, stable performance;b) Low pressure loss, able to save needed energy when transmitting the fluid;c) No need of real flow calibration when the nominal diameter is between 50mm to 1200mm. When the range is overstepped,

design and manufacture according to the reference proportion; when high precision is required, do real flow calibration;d) The body dimension is relatively long, for instruments with large drift diameter, transportation and installation are not convenient.
