A refrigerant flow meter must do something a water flow meter does not: handle a fluid whose density swings from 30 kg/m³ in the suction line to over 1300 kg/m³ in the liquid line of the same chiller. That density Read More
A piston flow meter measures liquid by counting how many fixed-volume slugs pass through the meter body. Each rotation of the piston pushes one chamber of liquid past a sealed reference, and a magnet on the piston shaft drives a Read More
A solid flow meter measures the mass flow of dry bulk material — cement, soybean meal, fly ash, plastic pellets, sugar, mined coal — moving through a pipe, chute, or on a belt. Unlike liquid flow, there is no single 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
Updated on April 25, 2026 — “Can I install this flow meter vertically?” is the wrong question. The right one is: which meter, and in which direction? A turbine installed downflow destroys its bearings in months. A rotameter installed horizontally Read More
Updated: April 24, 2026 — by Sino-Inst Engineering Team Molasses, honey, syrup, resin, and asphalt all share the same headache: they stop common flow meters from working. Orifice plates clog. Electromagnetic meters read zero when the fluid is non-conductive. Turbine Read More
Updated: April 23, 2026 Every differential pressure flow meter — orifice plate, venturi, flow nozzle, V-cone, averaging pitot — runs the same equation. Bernoulli says the velocity through a restriction goes as the square root of the pressure drop. Multiply Read More
Updated: April 22, 2026 A 6-inch (DN150) flow meter sits in a specific sweet spot — large enough to handle plant-scale cooling water, wastewater, and district heating loops, but small enough that you still have five mainstream technologies to choose Read More
Updated April 20, 2026 by 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
Updated April 20, 2026 by Sino-Inst Engineering Team Metering steam is expensive. Temperatures above 180 °C, saturated vs superheated corrections, and dropout from wet steam all push cost and error up. One pound of condensate equals one pound of steam Read More
