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

Sulfuric acid storage tanks combine three measurement obstacles: corrosive vapor in the headspace, concentration-dependent material compatibility, and regulated overfill protection. Direct-contact float and capacitance probes corrode within months. Non-contact 80 GHz radar with the right antenna material handles 96-98% concentrated Read More
Blast furnace stockline measurement runs at 1200 °C inside, with dust, hydrogen-rich gas, and constant charging dynamics. Mechanical sounding rods and isotope sources have given way to 80 GHz FMCW radar as the standard since around 2018. This guide covers Read More
A water tank level sensor is the small instrument that turns “how much water is left” into a number a pump controller, PLC, or phone app can read. The right choice depends on tank material, fluid type (potable, rain, waste, Read More
An ultrasonic CO2 level indicator is a portable handheld tool that confirms how full a CO2 cylinder is without removing it from service. A technician presses the probe against the outside of the cylinder, runs it up and down, and Read More
An underground tank level indicator measures the liquid depth inside a buried tank — fuel, potable water, septic, or chemical — and shows it on a gauge, panel, or remote dashboard. The right indicator depends on the fluid, tank depth, Read More
A stilling well is a metal pipe installed inside a tank with calibrated holes near the bottom. It surrounds the radar antenna (or any non-contact level transmitter) and dampens the surface chaos — foam, turbulence, swirls from agitators — that Read More
Contents Six technologies for powder level measurement Why powders are harder than liquids Radar for powders: 80 GHz, 26 GHz, and guided wave Vibrating fork and rotary paddle for point level Capacitive, RF-admittance, and ultrasonic alternatives Point level vs continuous Read More
Choosing an ultrasonic level sensor for diesel tanks is a tank-geometry problem before it is a sensor-spec problem. The same 4–20 mA transmitter that reads cleanly on a 3 m vertical cylindrical AST can drift, foam-out, or echo the wrong Read More
