LWG type turbine flow sensor and receiving electrical signals of
the display instrument of turbine flowmeter, which is used to
measure low and medium viscosity closed pipes
Degree of fluid (liquid or gas), the total volume flow and in
petroleum, chemical industry, metallurgy, aviation and scientific
research departments for a wide range of applications.
Sensor is composed of turbine sensor components and amplifier, the
structure of the two together for one-piece: to measure the
structure of the positive and negative flow
For two-way type; With inserted rod can be installed in the large
diameter pipe flow body flow structure for a plug-in.
Based on the principle of moment balance sensor work. When the
fluid flows through the sensor, promote the impeller rotation, when
the flow rate must be dynamic torque
Maintain and drag torque balance, the impeller speed. Evenly
distributed on the permeability of the impeller blade with the
impeller rotation, to periodically change detection
The reluctance of the magnetic field sensor (coil), electrical
pulse signal detector, after the amplifier amplification output.
The output electric pulse frequency and impeller speed
Is proportional to the impeller speed is proportional to the flow
in, so the output electric pulse frequency is proportional to the
flow sensor flow, 4-20 ma signal is converted is proportional to
1) impurity resistance is strong, tangential impeller rotating at
can release floating debris in the fluid at any time, when the
winding on tangential impeller blades.
2) resistance to electromagnetic interference and strong vibration
3) the structure and principle of the sensor and display instrument
is very simple, user especially easy to master its use and
4) after replacement of impeller and bearing, meter coefficient is
5) wide flow range, lower limit velocity is low.
6) complete sets of flow meter for the measurement of the fluid
volume error is small.
7) almost no pressure loss, save power consumption.
8) sensor can be installed in open air, the sensor can be submerged
in the water use for a long time.
9) have a globe valve sensor, install and remove all don't need to
10) horizontal, vertical, inclined pipe can be used.
11) complete sets of flowmeter the purchase, installation, and low
The main parameters:
Pulse output, linear characteristic; High precision, responsive;
Measurement of wide flow rate range
Signal output, pulse output (+ 12 + 24 VDC power supply, three wire
system) pulse output (+ 24 VDC power supply, two wire) 4-20 madc
simulation flow signal output
