Hoffer Flow Controls Hoffer Flow Controls Recognized for being able to design and build Recognized for being able to design and build custom flow meters in a short time. custom flow meters in a short time. Examples of custom design requirements Examples of custom design requirements include high pressure requirements (as much as include high pressure requirements (as much as 60,000 PSIG), exotic alloys, ultra ‐ ‐ high velocity high velocity 60,000 PSIG), exotic alloys, ultra flow measurement applications (Mach 0.5) and flow measurement applications (Mach 0.5) and designs for harsh environments (subsea to designs for harsh environments (subsea to 15,000 FT). 15,000 FT). 10
Turbine Flow Meters Turbine flow meters measure velocity. They work well in clean, low to mid ‐ viscosity applications. Liquid meters typically designed to measure up to 20 feet per second. Gas meters are designed to measure velocities as high as 250 feet per second. 11

Basic Definitions A measure of the accuracy of the device which LINEARITY: is the maximum percentage deviation from the average K-Factor. The number of output pulses the flowmeter K-FACTOR: produces per engineering unit of the volume throughput. A statement of the ability of a measuring device REPEATABILITY: to display the same value of a measured variable under identical conditions. 14
