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 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
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
The tuning fork density meter is an inline vibrating-fork sensor that measures liquid density from 0 to 2500 kg/m³ with ±1 kg/m³ accuracy. The fork tines sit directly in the process line — their resonant frequency shifts with the density Read More
Measuring level in an underground tank is harder than measuring an above-ground tank. You can’t just drop a sight gauge on the side. After the tank is buried, you’re stuck with whatever nozzles, manholes, and sensors were specified at install Read More
An ultrasonic CO2 level indicator is a portable, non-contact device that tells you how full a liquid CO2 cylinder is without opening it, weighing it, or puncturing the wall. You hold the probe against the outside of the cylinder, press Read More
Upstream and Downstream Straight Pipe Requirements for Flow Meters Updated April 2026 — By Sino-Inst Engineering Team Straight pipe length is one of the most overlooked variables in flow meter accuracy. The 10D upstream, 5D downstream rule appears in nearly Read More
