7. Application to high pressure measurement
When the measured liquid flows through the sensor, as the vane is at a certain angle with flow direction, driving
torque to the vane wheel will be formed. After overcoming friction torque and flow resistance torque, the vane
wheel starts to rotate and the speed will turn stable after torque balance. In a certain condition, the speed of the
vane wheel is in direct proportion to the velocity. As the vane is magnetic conductive in magnetic field of signal
detector, the rotating vane periodically changes the magnetic flux of coil by cutting magnetic lines, in which way
pulse signal can be induced at coil end. The pulse signal will be sent to the display to show flow rate or total rate
after amplified by magnifier.
In a certain flow range, pulse frequency f is in direct proportion to liquid flow rate Q with equation as below:
In which
f is the pulse frequency
k is the instrument coefficient of sensor(1/m2), which shows in testing report. If coefficient in (1/L),
Q is flow rate of liquid under working status (m3/h or L/h)

display to show flow rate and total rate.

■ Summary
■ Working Principle
■ Features
SGT Series GAS Turbine Flowmeter is a kind of velocity instrument,
which is characteristic of high precision, good repeatability,
simple structure, wide measuring scope, compact volume, light
weight, small pressure loss, easy maintenance, etc. It can
be used widely in petroleum, chemical, metallurgical, urban gas
network industries and so on. In particular, it has been extensively
used for the metering of urban natural gas, coal gas, LPG
(liquefied petroleum gas), light hydrocarbon gas, etc. in
transmission and distribution network and the metering of gas
pressure regulating stations.
7. Perfect protection and explosionproof function. Protection class IP65 and explosionproof label ExiaⅡCT6Gb.
SGT Series Gas Turbine Flowmeter is designed to set the turbine in the gas flow to be measured and when
the gas flows through the flowmeter, the gas is rectified and accelerated under the function of the
rectifier in a special structure. As the vane is at a certain angle with flow direction, driving torque to the
vane wheel will be formed. After overcoming friction torque and flow resistance torque, the vane wheel starts
to rotate. In a certain flow rate scope, the angular speed of the vane wheel and the flow rate are
proportional. Pulse signal in direct proportion to the gas volumetric flow rate can be induced by using the
electromagnetic induction principle. The pulse signal is amplified, filtrated, trimmed and then sent to the
integrating instrument for calculation, together with the signal detected by the temperature/pressure
transducer. Meanwhile the volumetric flow rate and total flow of the gas will be displayed on the LCD screen
directly.
