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
Flow rate and pressure are linked by Bernoulli’s equation, by friction losses, and by the geometry of whatever the fluid passes through. A pump that delivers 200 kPa across a 50 mm pipe will not push the same volume per minute Read More
Updated Apr 25, 2026 — Reviewed by Sino-Inst Engineering Team A BTU meter for chilled water quantifies cooling energy by combining a flow meter with a matched pair of RTDs on the supply and return. On a typical HVAC loop Read More
The K-factor of a flow meter is the number of pulses the meter generates per unit volume of fluid passing through it. It is a calibration constant that converts raw pulse counts into actual flow volume. Every pulse-output flow meter Read More
GPM and LPM are the two flow-rate units you will see on every industrial pump, valve, and flow meter datasheet. GPM is gallons per minute (US-spec by default). LPM is litres per minute. Converting between them is a single multiplication, Read More
Most flow meter accuracy problems trace back to one root cause: not enough straight pipe before and after the meter. Get the upstream and downstream lengths right and a $3,000 magmeter holds its ±0.5% spec. Get them wrong and even Read More
A magnetic flow meter (magmeter) measures conductive liquid by Faraday’s law: when fluid moves through a magnetic field generated by the meter’s coils, electrodes pick up a voltage proportional to velocity. The physics is unforgiving — an air bubble at Read More
