Flow Meters & Transmitters

filter_list

Flow meters and transmitters are crucial instruments used in a wide variety of applications to measure the flow of fluid, which can be a liquid or gas. They can be categorized into many types, including volumetric flow meters, differential pressure flow meters, and Venturi flow meters, each with their specific use cases and measurement techniques.

Flow transmitters take the measurements from the flow meters and convert them into a signal that can be read by control devices. This signal can be transmitted to a remote location for monitoring and control, making a flow transmitter especially useful in situations where the flow meter is located in a difficult-to-reach or hazardous location.

The integrated electronic circuit in these devices helps to ensure accurate and reliable readings. Some systems may also have multiple tubes for different flow measurements or for redundancy to ensure the accuracy and reliability of measurements.

More Information about Flow Meters and Transmitters

Volumetric Flow Meters

Volumetric flow meters, as the name suggests, measure the volumetric flow rate of a fluid, providing data about the volume of fluid passing through the device per unit of time. These meters can be used in several industries, from water treatment to oil and gas, to ensure the correct fluid quantities are being used or processed.

Differential Pressure Flow Meters

Differential pressure flow meters, on the other hand, work by creating a pressure drop across a mechanical body such as orifice plates, flow nozzles, or venturi, and measuring this difference in pressure. This pressure difference can then be used to infer the rate of fluid flow. An orifice plate is a common type of differential pressure flow meter, and consist of a flat plate with a specific hole size that the fluid must pass through, causing a drop in pressure.

Flow meters and transmitters have a significant impact on industries such as oil and gas, petrochemicals, water treatment, and more, as they enable precise flow measurement and control, ensuring efficiency and safety in various operations.

FAQs

What is the best way to monitor fluid flow in a small pipe that is operated remotely?

The best way to monitor fluid flow in a small pipe that is operated remotely would be to use a flow meter such as, an ultrasonic flow meter, an electromagnetic flow meter, a turbine flow meter or a positive displacement meter, and connect it to a flow transmitter, which converts the flow rate into a standard signal that can be transmitted and monitored remotely.

 

Mag Flow Meter Basics 

Flow meters measure the flow of a substance through a pipe. Based on the size of the pipe, the flow meter measures the volume of the substance and how fast it is moving through the pipe. 

How it Works

Mag flow meters measure voltage levels of a liquid that is flowing through a pipe. The Mag flow meter is installed in line with the pipe and the diameter of the pipe should be the exact same size as the pipe carrying the liquid.

Within the flow meter piping, there are two field coils located on opposite sides of each other. These field coils will generate an electromagnetic field over the entire cross section of the measuring pipe of the flow meter. Two electrodes that measure voltage are installed in the flow meter on opposite sides of the field coils. These electrodes measure any voltage present in the fluid flowing through the mag flow meter.

When fluid starts to flow through the meter, the electromagnetic field will apply a force to the charged particles in the fluid. The positively and negatively charged particles begin to collect on opposite sides of the flow meter piping, forming an electrical voltage. The voltage will be directly proportional to the flow moving through the piping. The higher the voltage, the higher the flow velocity in the pipe. With this information, as well as the cross-sectional size of the pipe, the total volume of fluid that is flowing through the pipe can be calculated.
