LWL11Y liquid turbine flowmeter is a new generation of turbine flowmeter that absorbs the advanced technology of flow meters at home and abroad and is optimized and designed, with simple structure, light weight, high precision, good repeatability, sensitive response, easy installation, maintenance and use. Only the volume and mass flow rates of impurity-free and non-corrosive liquids can be measured. There are various connection methods such as flange connection, threaded connection, clamp connection, chuck connection, etc. There are also battery-powered, explosion-proof and other functions to choose from.
