I. General
1.1 Introduction
TRFM 1.0 turbine flow meter consists of turbine flow sensor and display instrument
and it is made by us using foreign state-of-the-art technologies, which is an ideal
gauge for measuring of liquid flow.
The flow meter is characterized by simple structure, high precision and easy
installation and repair. The product may be used in a wide range of industries,
including oil industry, chemical industry, metallurgy, water supply, paper-making,
environment protection and food industry.
It is applicable for use in closed pipes to measure flow of liquid which will not erode
stainless steel (1Cr18Ni9Ti), 2Cr13, Al2O3 and hard alloy and is free of impurities
such as fiber and granules. If this product is used in association with display
instruments with special functions, it can be used for purpose of automatic definite
quantity control and alarming in case of excessive amount.
1.2 Product Features

1.3 Working Principle
When liquid flows through the casing of sensor, the impulse of fluid will provide the
blade with a rotation moment as there is an angle between the blade of impeller and
the flow direction. The blade will rotate as the friction moment and the fluid
resistance are overcome and it will reach a stable speed when the moments are at
balance. Under certain conditions, the rotation speed of blade will be in direct
proportion to the flow velocity. Due to the magnetic conductivity of blade, when
located in the magnetic field generated by signal detector (made of permanent magnet
steel and coils), the rotating blade will cut the magnetic lines and periodically change
the flux through the coil, thereby inducing electrical impulse signals at both ends of
the coil. The induced signals, after amplified and rectified by amplifier, will form a
continuous rectangular impulse wave with certain amplitude which may be remotely
transmitted to display instrument indicating the instant flow and the cumulative flow
of fluid. Within a certain range of flow, the impulse frequency f is in direct proportion
to the instant flow of fluid flowing through the sensor, which is shown in the equation
below:
k
f
Q 3600
Wherein:
f- Impulse frequency [Hz];
k- Instrument factor of sensor [1/m3], which is given by checklist. If [1/L] is used as
the unit, the equation will be:
k
f
Q 6.3
Q- Instant flow of liquid (in operation) [m3/h];
3600- Conversion factor.
Instrument factor of each sensor will be filled out in verification certificate by the
manufacturer. The instant flow and cumulative flow will be displayed when the value
of k is loaded into associated display instrument.

In case of open air installation, water proof measures shall be taken for purpose of
amplifier and plug of the sensor. The wiring between sensor and display instrument is
shown in Fig. 5.
When fluid contains impurities, filter shall be additionally installed. The number of
