Turbine Flow Meter Discription
The NYLU-JB vortex flow meter is researched and produced according to the principle of Karman vortex flow, and is mainly used for flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. The vortex flow meter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃~+250℃. There are analog standard signals and digital pulse signal output, which is easy to be used with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
◎The measurement accuracy is high, the reliability is high, and no on-site debugging is required.
◎It can transmit traffic signals over long distances, and can be networked with computers to achieve centralized management.
◎The amplifying board adopts a unique design, which can be used for both gas and liquid.
◎There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers.
◎Explosion-proof instruments can be used in corresponding explosion-proof places.
◎Customized design and production according to customer requirements.
