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 4-20 mA current loop carries a sensor signal across hundreds of meters with near-zero drift. A 0-10 V PLC card cannot accept that current directly. Converting between the two is a five-cent fix on the bench (one resistor) or Read More
Updated May 21, 2026 — Yes, most flow meters can run on a vertical pipe — but only if you pick the right type and respect the orientation rules. A magnetic meter mounted with horizontal flow shows zero. A turbine Read More
Updated May 21, 2026 — A condensate flow meter sits on the return side of a steam loop and measures the hot, sub-cooled water flowing back to the boiler feed tank. Pick the wrong technology and you will see negative Read More
Updated May 21, 2026 — A pressure transmitter is only as accurate as its installation. Mount it on the wrong elevation, route impulse tubing without a proper slope, or skip the root valve and you will chase phantom readings for 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
A pressure transmitter drifts. Diaphragm fatigue, temperature swings, vibration, and process buildup move the zero and span over time. A 0.1 % drift on a 0–1.6 MPa range puts the loop 1.6 kPa off — enough to trip a safety interlock or skew Read More
Pressure is force per unit area, but the unit you put on a gauge depends on the industry, the country, and the instrument. A process plant in Asia reads MPa, an HVAC tech reads inches of water column, a hydraulic 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
A Karman vortex air flow sensor measures the frequency of vortices shed behind a bluff body in a moving air stream. Frequency is proportional to flow velocity, so counting vortices gives a direct, moving-parts-free reading of mass air flow. Automotive Read More
