Gas flow switches and liquid flow switches, velocity, are devices used for measuring the flow or quantity of a moving fluid in terms of velocity, such as feet per minute. These may be plain sensors or sensor systems with displays and computer outputs. The most important specifications for velocity style gas flow switches and liquid flow switches are the flow rate to be measured and whether liquids or gases will be the measured fluids. Also important are operating pressure of the fluid line, the fluid temperature and accuracy. The technologies for velocity gas flow switches and liquid flow switches vary widely. |
Products & Services Related to Velocity Flow Switches
Gas Flow Meters
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.
Gas Flow Switches, Volumetric
Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute.
Liquid Flow Meters
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
Liquid Flow Switches, Volumetric
Volumetric liquid flow switches are devices with a switch output used for measuring the flow or quantity of a moving fluid in terms of a unit of volume per unit time, such as liters per minute.
Mass Flow Meters and Controllers
A mass flow meter is a device that consist of a mass flow sensor or transducer and signal processing electronics. Fluid (liquid or gas) flow is measured in mass rate units (lbs/min).
Mass Flow Switches
Mass liquid flow switches and mass gas flow switches are devices used for measuring the flow or quantity of a moving liquid or gas in terms of a unit of mass per unit time, such as pounds per minute. These devices may be sensors with electrical output or may be stand-alone instruments with local displays and controls.
Ultrasonic Flow Meters
Ultrasonic flow meters use sound frequencies to determine flow rates. They do not work well with liquids with suspended solids or air gaps.
