EXPERIMENT 7 - TURBINE METER
Aim: To draw the calibration curve by plotting a graph between
actual flow discharge (Q act) and Observed flow discharge (Qobs).
Apparatus Required: Flow Bench with Turbine Meter
The principle of turbine flow meters has something to do
with pipes, blades, and rotor. The rate of flow in pipes has been
flowing on pipes via a rotor that spins and this flow has passed on
its blades and the thing on this measurement is called turbine flow
meter. Mathematically a direct function of flow rate is the rotational
speed of the rotor in pipes is and this can be sensor by its
magnetic pick-up, photoelectric cell or gears.
There are volumetric turbine flow meter and velocity
turbine flow. These are basic classification types of this flow meter
and have different units, mL/min for volumetric turbine flow and
ft./sec for velocity turbine flow. Classification of Volumetric turbine
flow can be in a state of gas or liquid and can be-be critical need
for measurement in many industrial plants so that it has an
accurate flow of measurement, for business to have gain profit on
this operation in industries. Inaccurate measurement can result in
distrust of people in their company. So as of be carefulness, there
are important parameters to consider when specifying turbine flow
meters include velocity flow rate range, liquid volumetric flow rate,
operating pressure, fluid temperature, material density, and
material viscosity in order to have met its accuracy. On the other
types, velocity flow applies sensor. rate range applies only to those
turbine flow meters that are velocity flow sensors or meters.
Importance of this can be maximized its accuracy, include
the parameter of pressure. Viscosity is an important role for this
that make include on a process on turbine flow measurement. It’s
dependable on materials needed that turbine can be stand or
withstand like in turbine exposure at some temperature. In relation
to viscosity, the higher viscosity, the higher pressure drops, or
lower viscosity the lower
pressure drops so selection
material must be considered
as used. Also, the pipe
diameter is important to use.
i) Before turning on the power of the network, open the flow / water
level of the bypass valve.
ii) It is necessary to close the valves of the collection containers (1,
2, 3, 4) and (1, 2, 3) and open the drain.
iii) Open the exhaust valve and align the selector switch to the third
iv) Turn on the electri...
