Davis Instruments offers an extensive range of flow meters and flow controllers for both liquid and gas applications. Davis Instruments specializes in flow control of media in pipe lines less than 2" and offers flow metering solutions for measuring liquids flow from 0.0002 ml/min to over 4,000 LPM and for gases from 0.02 ml/min to over 500 m3/hour.
Davis Instruments' flow meters come with a wide range of output options including set-point switches, analogue outputs 4-20 mA, 0-5 VDC, pulse signals and RS-232 options. Use Davis Instruments' flow meter quick search to find the right flow meter for your application.

Flow Meter Selection Considerations
When selecting a flow meter consideration must be given to:
- Flow measurement type - momentum (velocity), volumetric or mass flow measurement
- Media - type of media (liquid, gas or slurry) and any special condition such as particulates in the media and viscosity of the media
- Media conditions - pressure and temperature of media and whether media conditions are likely to remain constant or vary
- Flow range - required flow range of media (min and max readings required)
- Accuracy - required accuracy of the readings
- Environmental considerations - special installation considerations such as hygienic installation, installing in to an ATEX zone or requiring tamper proof readings
For special or unique flow control applications

Each time the flag waves there's a pulse. A vortex flow meter measures the pulses which are proportional to the rate of flow. Many users find the technology appealing because it has no moving parts. Because the meter body and vortex bar can be molded as one, this design is ideal for making meters for use in aggressive or high-purity applications, and are used in utilities, water and wastewater treatment, steam handling, and natural gas measurement. Steam handling requires an RTD for temperature measurement as mass, not flow, is measured in that application. Davis Instruments offers vortex flow meters from ABB and UFM for heavy industrial applications and from Clark Solutions for light-duty use.
