Updated May 28, 2026 · Sino-Inst Engineering Team A residential water meter looks simple from the outside — a brass body, a glass face, a few rolling digits. Inside, it is doing one of three jobs: filling and emptying a Read More
Updated May 26, 2026 | Sino-Inst Engineering Team Choosing an ammonia flow meter starts with one question: is the NH3 liquid, gas, or switching between both? Each phase demands a different meter technology. Anhydrous liquid ammonia pressurized to 10 bar Read More

The K-factor of a flow meter is the number of output pulses the meter generates per unit volume of fluid. It is the calibration constant that lets a turbine, vortex, or paddle-wheel meter convert its raw frequency into engineering units Read More
GPM and LPM are the two flow-rate units printed on almost every industrial pump, valve, and flow meter datasheet. GPM means gallons per minute (US gallons unless the label says otherwise). LPM means litres per minute. The conversion between them Read More
Updated May 21, 2026 — Yes, most flow meters can run on a vertical pipe — but only if you pick the right type and respect the orientation rules. A magnetic meter mounted with horizontal flow shows zero. A turbine Read More
Updated May 21, 2026 — A condensate flow meter sits on the return side of a steam loop and measures the hot, sub-cooled water flowing back to the boiler feed tank. Pick the wrong technology and you will see negative Read More
A Karman vortex air flow sensor measures the frequency of vortices shed behind a bluff body in a moving air stream. Frequency is proportional to flow velocity, so counting vortices gives a direct, moving-parts-free reading of mass air flow. Automotive Read More
A chilled water flow meter measures the flow rate of cooling fluid in an HVAC plant, district cooling loop, or industrial process chiller. The right meter type depends on pipe size, accuracy class, glycol content, and whether the reading feeds Read More
