Variable Area Flowmeter LZS


Metal Tube Rotameter is a Variable Area Flow Meter. It consists of a tapered tube, typically made of steel with a 'float', made of SS or PTFE. It adopts full metal structure, which is with the features of small volume, low pressure loss , big range ratio(10~20:1),optional transmitter with HART communication function, installation and low maintenance convenient. It is widely used in various industries under the complex and bad environment, which is measuring the flow and controlling the process to the small flow and low flow velocity, and all kinds of harsh conditions of medium.

Product Feature
