Differential Pressure Flow Meters – Refinery and oil and gas industries are largely dependent on differential pressure flow meters for their liquid flow measurement applications. Like many other flow meter equipment, this unit also contains a primary and a secondary element. The purpose of the primary element is to introduce a constriction in the pipe that contains liquid. As a result of this constriction, differential pressure is created in the pipe. The secondary element in the unit measures this pressure differential, and accordingly determines the fluid flow. The fluid flow rate is then displayed on the monitor.Differential pressure meters are available in several types. These include; orifices, venturi tubes, flow tubes, flow nozzles, elbow-tap meters, target meters, and variable-area meters. Application users must select the right type after analyzing the pipe’s size, flow conditions, and nature of liquids. Positive Displacement Flow Meters – This flow meter type offers unmatched service for measuring the flow of viscous liquids. It is brilliantly designed to directly measure the liquid flow as and when it passes through the flow meter. The unit entraps fluid when it is moving through the flow meter. This equipment is ideal to measure the flow of petrochemicals, adhesives, and paints.Some of the advantages associated with this unit include: high accuracy, low pressure drop, self-contained operation, low operating costs, and long service life. Positive displacement flow meters are largely utilized for precision flow meter applications in chemical, power, pharmaceutical, and food processing industries.There are several types of displacement flow meters available for industry specific applications. These include, reciprocating piston, oval gear, nutating disk, and rotary vane meters. Velocity Flow Meters – These types of flow meters are largely procured for applications in power generation, waste water treatment, chemical and refinery industries. They can be directly connected to pipelines to operate linearly with respect to the flow rate. Directly attached to pipelines, these units are supplied with flanges or fittings. Some of the advantages of these units include: fixed pressure loss at all flow rates, outstanding accuracy when used with low-viscous fluids, reliable operation over a wide range of pressures and temperatures.Velocity meters are available in several types. These include, turbine and paddle wheel, ultrasonic, electromagnetic, vortex-shedding, and Doppler ultra-sonic flow meters. Mass Flow Meters – When precise measurement of mass rate of a liquid is your requirement, then mass flow meters are the ideal solution. Unlike differential pressure meters, which measure volumetric flow, this unit measures the mass rate of the flow in a pipe. These flow meters are largely used for measuring liquids whose viscosities vary with velocity. Some of the advantages of these systems include: reliable operation over a wide range of pressures and temperatures, and extremely high accuracy.Mass flow meters are available in two types, namely, coriolis and thermal-type mass flow meters. Open Channel Meters – As the name implies, these types are ideal for measuring liquid flow in open channels. These units enable continuous and precise flow rate monitoring in tunnels, partially filled pipes, canals, streams, and rivers. Some of the advantages associated with these units include, versatile modular system, unparalleled accuracy, easy-to-install design.

Applications of venturimeter?
1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.
why are flow meters used on a chilled water system.?
The cooling effectiveness of the chilled water system depends on the water flow. Thus the water flow rate, as well as the temperature of the water, need to be monitored and adjusted to provide the chilling effect.

What is the difference between a flow meter and a flow transmitter?
In the fluid transmission system, several types of devices are used to measure and control the process parameters. The flow meter and the flow transmitter are two important devices used in such systems. For some reason, these two devices are often considered the same. Sometimes their functions are interchanged. However, in reality, both these devices and their functions are quite different than each other. This post introduces the flow meters and the flow transmitters individually and helps you to understand the difference between these devices. Let us discuss both flow meter and flow transmitters individually to you understand their concepts thoroughly. A Brief Introduction to Flow Meter A flow meter is an instrument designed for measuring the rate of fluid flow via a fluid transmission system. It measures the flow rate of a fluid, liquid, or gas when it passes through a confined transmission system. There are different types of flow meters like orifice meters, venturimeters, rotameters, flow nozzles, etc. These different flow meters have different functioning principles. For example, an orifice meter calculates the flow of fluid at the entrance cross-section of a narrow, restricted opening called orifice and at the exit cross-section of the same. On the other hand, a rotameter type of flow meter that measures the volumetric flow rate inside multiple tubes placed at different areas of the transmission pipe. What is a Flow Transmitter and How it Works? A flow transmitter is an upgraded version of the flow meter. It is a flow meter with an integrated electronic circuit as an operational system. In the flow transmitter, the activity of flow rate measurement is performed by the electronic circuit on receiving the commands from the operator. Since the flow transmitters feature an electronic circuit, it is possible to control and monitor the fluid flow using these devices. Differences between the Flow Meter and Flow Transmitter The following are a few significant differences between flow transmitters and flow meters. The flow meters’ are designed to measure the flow rate. On the other hand, the flow transmitters not only measure the flow rate but also help in controlling and monitoring it. The flow meters are standard mechanical systems like orifices, venturimeters, etc. The flow transmitters on other hand feature a mechanical body and electronic functioning circuitry. The flow meters are designed for manual, on-field applications, however, the flow transmitters can be remotely operated. Now that the differences between the flow transmitters and flow meters are known, you can select the suitable one for you. Certainly, flow transmitters can be helpful in measuring, monitoring, and controlling the flow rate if your application requires it all. However, the quality of the products can make a huge impact on your application, so you must buy from trusted manufacturers or suppliers like The Transmitter Shop. The company provides new surplus and factory new flow transmitters & meters like Rosemount flow transmitters, Foxboro flow transmitters, Rosemount vortex flow meters and so on.
