It could be volumetric or mass flow rate the medium could be gas or liquid the measurement could be intrusive or nonintrusive and so on.
Liquid flow measurement devices.
The device is placed in a moving liquid with the lower opening directed in the upstream direction.
The velocity is the pressure differential which forces the liquid down the conduit or pipe.
These measurements are related by the material s density the density of a liquid is almost independent of conditions.
There are many types of liquid flow measurement devices.
This flow device is.
Flow measurement page 3 rev 1 0 9 xx 06 mitchell cottrell device that has been in use for measu hese plates are generally installed by trapping it e plate he calculation for incompressible liquid flow is the equivalent of the notch weir in a tube would be an orifice plate.
This flow meter is very practical capable of being used as a liquid flow measuring device as well as with liquids and steam flows.
This kind of meter accumulates the.
Innumerable ways of measuring a liquid can be employed among which the positive displacement devices are worth to be mentioned.
Our product finder helps you to search for suitable measuring devices software or system components via product characteristics.
A common method of measuring flow through an open channel is to measure the height of the liquid as it passes over an obstruction as a flume or weir in the channel.
Rangeability turndown ratio for flow measurement devices like orifices venturi meters etc.
Since the cross sectional area of the pipe remains constant and is known the typical velocity indicates flow rate.
Flow measurement for liquids gases and steam.
As a result accurate measurement of flow rate is very important.
In its simple form the pitot tube consists of a glass tube whose lower end is bent at right angles fig.
Common used is the sharp crested weir the v notch weir.

Needless to say that there could be diverse requirements of flow measurement depending upon the situation.
Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates with units such as liters per second or kilograms per second respectively.
Liquid flow measurement devices rely on the velocity of the liquid being measured.
Kinds and units of measurement.
You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters.
Achieve precision flow measurement and process control flow measurement is the process of measuring fluid in your plant or industry.
Flow measuring device 2.
In order to bill the quantity of liquid or gas transfer a flow meter is regarded to be the most vital device.
A measurement is achieved at every juncture where a transaction occurs.
