Product Description
High-Performance Oval Gear Flowmeter
The circular gear flowmeter belongs to a type of volumetric flowmeter. Flowmeter is a volumetric meter used for the continuous or discontinuous
measurement and control of liquid flow in pipeline, which has many advantages such as wide range of measurement, high accuracy, small pressure loss, strong viscosity adaptability, high temperature and high viscosity liquid measurement, convenient calibration, installation suggestions and so on. It is applicable to the flow measurement of petroleum, chemical industry, chemical fiber, transportation, commerce, food, medicine and health and other departments.
LW series cylindrical gear flowmeter is equipped with pulse transmission and digital LCD meter device. It can not only provide the stable and accurate
pulse signal output, the instantaneous, accumulated liquid flow directly, and provide a variety of signal remote transmission function. It can also be matched with the electric display instrument to realize the remote transmission and centralized control of cumulative, quantitative and instantaneous flow, but also measure the liquid with high temperature and high viscosity. The excellent performance of the circular gear flowmeter can be well adapted to the various complex working conditions.
It can be based on the different liquids (acid, alkali, salt, organic solution, etc.) to choose different materials to manufacture the flow meter body.

Specification
The rotational speed of the circular gear flowmeter is measured by
a sensor coil in a signal amplifier mounted on the case, which is not in
contact with the measured medium. A change in the flux in the sensing coil
is caused when the transmitter gear cuts the lines of force produced by
the permanent magnet in the housing. The detected flux periodic change
signal is sent to the preamplifier by the sensor coil, which amplifies
and reshaps the signal, and generates a pulse signal proportional to the
flow rate. The pulse signal is fed into the unit conversion and flow
integrator circuit to obtain and display the cumulative flow value, while
the pulse signal is fed into the frequency current conversion circuit to
convert into analog current, and the instantaneous flow value is
indicated.
The circular gear flowmeter has the characteristics of high machining
accuracy and precise installation. The rotation of the gear is scanned
by non-contact, and each tooth generates a pulse with very high resolution.
Very small flow, quantitative small volume of liquid can be measured by
the cylindrical gear transmitter.
