Updated May 27, 2026 | Sino-Inst Engineering Team A tank level monitoring system is not a single sensor — it is three layers: the level sensor, the 4–20 mA or HART signal, and the recorder or SCADA that turns the Read More
Updated May 27, 2026 | Sino-Inst Engineering Team For pressure transducer wetted parts, the choice between 316L and 17-4PH stainless steel is the single most important spec you put on the RFQ. 316L is the default for clean liquid, hydrogen, Read More
Updated May 27, 2026 | Sino-Inst Engineering Team Hydrostatic pressure is the pressure a liquid exerts on a point below its surface, equal to density × gravity × depth. In SI units, P = ρgh — and that single equation Read More
Updated May 26, 2026 | Sino-Inst Engineering Team A submersible pressure transducer measures the hydrostatic head of liquid above its diaphragm and reports it as a 4–20 mA, 0–5 V, or RS485 signal. Choosing one is not “pick the cheapest 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
Updated May 26, 2026 | Sino-Inst Engineering Team Most pressure transmitter troubleshooting calls trace to one of five things. A 4–20 mA transmitter with “no output” looks like a dead sensor, but it almost never is. In our field records, Read More
