Updated: April 23, 2026 Septic tanks, sewage holding tanks, and lift station wet wells are the dirtiest service for any level sensor. Solids settle on the bottom. Grease and FOG (fats, oils, grease) form a scum layer on top. Hydrogen Read More
Updated: April 22, 2026 Measuring level inside a blast furnace shaft is one of the hardest jobs in process instrumentation. The environment combines red-hot gas, dust clouds, pressure pulses, and electromagnetic noise. Guided-wave probes and mechanical plumb-bobs wear out in Read More
Updated: April 22, 2026 Sulfuric acid storage tanks are the worst-case scenario for level instrumentation. Concentrated H₂SO₄ corrodes 316 stainless, dilute H₂SO₄ corrodes differently but just as fast, and the vapor space is full of fuming droplets that coat any Read More
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
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
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
Last Updated: April 7, 2026 | Author: Wu Peng, Senior Instrumentation Engineer Stilling wells isolate radar antennas from surface turbulence, foam, and obstacles. When tanks have agitation or low-dielectric liquids, a properly sized well dampens noise and stabilizes signal. This Read More
Updated: April 16, 2026 | By Sino-Inst Engineering Team Most tank level sensor guides start with the sensor — radar, ultrasonic, hydrostatic, capacitance — and tell you what each one does. That is the wrong way around. The fluid you Read More
Updated: April 15, 2026 A capacitive liquid level sensor detects level by measuring the capacitance change between a probe and the tank wall (or a second probe) as the liquid rises or falls. The liquid acts as the dielectric — Read More
Updated: April 16, 2026 | By Sino-Inst Engineering Team A float switch on a water tank is just a mechanical contact in your pump’s power loop. When the float rises, the contact opens (or closes); the pump stops (or starts). Read More
