FLOW CONTROL AND MEASUREMENT

 

Flow measurement can be defined as quantification of the movement of water in a given channel. Flow can be measured either by determining the displacement and/or Velocity of the water. Water meters usually control measure and display total usage in cubic meters, on either mechanical or electronic registers. 

Flow can be divided into two main flows which are: Open channel flow and Closed conduit flow. Flow is controlled by use of valves at intervals to either to slow down, allow faster flow or completely shut down the flow. Some water meters usually perform both the function or making readings and controlling flow while others just conduct measuring only. 

Meters for reclaimed water contain special lavender register covers show that the water is non-potable. Velocity-type meters measure the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. Since Multi-jet meters are usually very accurate in small sizes they are normally used for residential and smaller commercial uses. Turbine meters are not as accurate as jet meters and displacement meters at low flow rates. 

A compound meter is used where high flow rates are necessary. Magnetic flow meters are a velocity-type water meter, except that they use electromagnetic properties to determine the water flow velocity. In water treatment plants, measurement and control devices can be installed in the following locations: within interceptors or manholes, the head of the plant, in the force mains that lead to main tanks etc. Automatic Meter Reading has compelled producers to build pulse or encoder registers to provide electronic output for radio transmitters, reading storage devices, and data logging devices.
