Components Of Liquid Flow Measurement Devices

This flow meter is very practical capable of being used as a liquid flow measuring device as well as with liquids and steam flows.

Components of liquid flow measurement devices.

Flow measuring device 2. In general we can split the fluids into two classes. The devices used to measure the mass or volumetric flow rate of a liquid or gas include mechanical flow meters differential pressure based meters variable area meters electromagnetic flow meters thermal mass flow meters and more. Many techniques are used to ensure the liquid flow rate measuring device is performing correctly.

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. A combination of one or more devices may also be used as part of a flow measurement process. Not measure your water use but may help the measuring device do its job. The primary devices used in open channel flow measurements are weirs and flumes.

In its simple form the pitot tube consists of a glass tube whose lower end is bent at right angles fig. Pessurer transducers these are capable of measuring the height of water as pressure increases with water depth. A pitot tube is a simple device meant for measuring the velocity of a liquid at any point. Kinds and units of measurement.

This measurement is then converted to flow using calculations developed specifically for the channel in which the device is installed. These measurements are related by the material s density the density of a liquid is almost independent of conditions. 1 1 types of flow measurement devices fluid flow devices fall into a number of device categories as well as fluid classes. Microfluidics refers to the behaviour precise control and manipulation of fluids that are geometrically constrained to a small scale typically sub millimeter at which capillary penetration governs mass transport.

The device is placed in a moving liquid with the lower opening directed in the upstream direction. There are many types of liquid flow measurement devices. Calibration in field proving and verification. Liquid flow measurement devices rely on the velocity of the liquid being measured.

Devices for open channel flow measurement. With the known landfill characteristics the flow is usually determined by the height of the liquid in. Weirs are openings in the upper part of a dam or reservoir that allow liquid flow and allow flow measurement. 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.

It is a multidisciplinary field that involves engineering physics chemistry biochemistry nanotechnology and biotechnology. Since the cross sectional area of the pipe remains constant and is known the typical velocity indicates flow rate.
