As a common precision instrument in modern industry, a turbine flowmeter is simply an instrument used to measure fluid flow in pipes or open channels. The development of measurement can be traced back to ancient water conservancy projects and urban water supply systems. In the ancient Roman Caesar era, orifice plates have been used to

Required Lengths of Straight Runs Flow altering devices such as elbows, valves, and reducers can affect accuracy. See the diagram below for typical flow meter system installation. The recommended guidelines are given to enhance accuracy and maximize performance. The distance given here are minimum requirements; double them for desired straight pipe lengths. Upstream: allow

A rotameter consists of a tapered tube, typically made of glass with a ‘float’ (a shaped weight, made either of anodized aluminum or a ceramic), inside that is pushed up by the drag force of the flow and pulled down by gravity. The drag force for a given fluid and float cross-section is a function

Small antenna size, easy to install; Non-contact radar, no wear, no pollution. Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature, and pressure changes. A serious dust environment on the high-level meter work has little effect. A shorter wavelength, the reflection of solid surface inclination is better. The
