Flow Rate Measurement Devices
Flow measuring device 4.
Flow rate measurement devices. Flowmeters and turndown ratio rangeability turndown ratio for flow measurement devices like orifices venturi meters etc. 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. However a variety of advanced equipment can also be used to sense stage and measure streamflow. These measurements are related by the material s density the density of a liquid is almost independent of conditions.
All of these. Kinds and units of measurement. The current meter is used to measure water velocity at predetermined points subsections along a marked line suspended cableway or bridge across a river or stream. In the simplest method a current meter turns with the flow of the river or stream.
For the measurement of flow rate of liquid the method used is a. The device is very simple and can be easily installed. Round ducts log linear traverse for round ducts two diameter approach. Flow nozzle and dall flow tube d.
Coefficient of discharge is 0 60 to 0 64. In this article we will try to look at each category with brief details of particular devices that fall under that category. Flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit. You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters.
The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially. The devices used for flow obstruction is are a. This is another device for the measurement of flow in pipes. Achieve precision flow measurement and process control flow measurement is the process of measuring fluid in your plant or industry.
