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 24, 2026 by the Sino-Inst Engineering Team A magnetic level gauge is a mechanical indicator that reads liquid level from the outside of a vessel using a magnetic float sealed in a bypass chamber. No power, no sight 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 23, 2026 Septic tanks, sewage holding tanks, and lift station wet wells are the dirtiest service for any level sensor. Solids settle on the bottom. Grease and FOG (fats, oils, grease) form a scum layer on top. Hydrogen Read More
Updated: April 23, 2026 A pressure gauge gives you a number on a dial. A how a pressure transmitter works sends a 4-20 mA signal to a control system. That single sentence drives 90% of the selection decision. The remaining 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 21, 2026 | Sino-Inst Engineering Team Most ultrasonic level transmitter problems are installation problems, not sensor problems. A sensor mounted 20 cm inside its own blanking distance will read zero no matter how good the electronics are. This Read More
Updated April 20, 2026 by Sino-Inst Engineering Team A 4–20 mA pressure transmitter with “no output” looks like a dead sensor, but it almost never is. In our field records, 80% of no-output calls trace to five things: wrong wiring 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 Apr 17, 2026 — Differential pressure (DP) flow measurement relies on a flow element — a restriction in the pipe that creates a pressure drop proportional to flow rate. But not all flow elements perform equally. Each type trades Read More
