Static, dynamic, and total pressure are three flavours of the same scalar — but they appear at different ports of a Pitot-static probe, drive different process instruments, and trip up new HVAC and fluid-mechanics engineers because the textbook prose hides Read More
GPM and LPM are the two flow-rate units printed on almost every industrial pump, valve, and flow meter datasheet. GPM means gallons per minute (US gallons unless the label says otherwise). LPM means litres per minute. The conversion between them 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 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
