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 pressure transmitter sends a 4-20 mA signal to a control system. That single sentence drives 90% of the selection decision. The remaining 10% is where Read More
Updated: April 22, 2026 Measuring level inside a blast furnace shaft is one of the hardest jobs in process instrumentation. The environment combines red-hot gas, dust clouds, pressure pulses, and electromagnetic noise. Guided-wave probes and mechanical plumb-bobs wear out in Read More
Updated: April 22, 2026 Sulfuric acid storage tanks are the worst-case scenario for level instrumentation. Concentrated H₂SO₄ corrodes 316 stainless, dilute H₂SO₄ corrodes differently but just as fast, and the vapor space is full of fuming droplets that coat any 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 21, 2026 | Sino-Inst Engineering Team The cheapest way to convert a 4-20 mA loop signal into a voltage for a PLC or recorder analog input is a single precision resistor in parallel with the input. A 500 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 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
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
