Liquid Flow Measurement Devices

There are many types of liquid flow measurement devices.

Liquid flow measurement devices.

Liquid flow measurement devices rely on the velocity of the liquid being measured. Since the cross sectional area of the pipe remains constant and is known the typical velocity indicates flow rate. This kind of meter accumulates the. A pitot tube is a simple device meant for measuring the velocity of a liquid at any point.

These measurements are related by the material s density the density of a liquid is almost independent of conditions. Only recently was approved a draft standard to its use in the industry in 2007 extended to 2010 and still has increasing popularity for future companies. Applicator leads you through an individual product selection via application parameters. 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.

This flow meter is very practical capable of being used as a liquid flow measuring device as well as with liquids and steam flows. Needless to say that there could be diverse requirements of flow measurement depending upon the situation. 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. In its simple form the pitot tube consists of a glass tube whose lower end is bent at right angles fig.

Flow measurement for liquids gases and steam. In order to bill the quantity of liquid or gas transfer a flow meter is regarded to be the most vital device. The velocity is the pressure differential which forces the liquid down the conduit or pipe. This flow device is.

The device is placed in a moving liquid with the lower opening directed in the upstream direction. Go to product finder. Common used is the sharp crested weir the v notch weir. Innumerable ways of measuring a liquid can be employed among which the positive displacement devices are worth to be mentioned.

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. Flow measuring device 2. You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters. Rangeability turndown ratio for flow measurement devices like orifices venturi meters etc.

Kinds and units of measurement. 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. A measurement is achieved at every juncture where a transaction occurs.
