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.
Turbine Flow Meter Design Features
◎Easy to install, simple structure, no moving parts.
◎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.
