Kaifeng Instrument AMH Metal Tube Variable-area Flow Meter (Rotameter)
Product Overviews
AMH adopts full metal structure, and is the modular metal tube variable-area flow meter with non-magnetic hysteresis, without any driving mechanism transmitter, mainly composes of two parts: sensor and indicator.
AMH series metal tube rotameter is applicable for the measurement and control and the flow of various fluids in gas or liquid state. Different types of rotameters can be selected for different working conditions such as high temperature, corrosive medium, different flow directions, hazardous environment and etc. AMH series rotameter is easy to install and operate and all the products will get through 100% inspection with pressure testing and real flow calibration before shipment.
