A transformer oil level indicator monitors mineral or ester insulating oil inside a power transformer’s main tank, conservator, or on-load tap changer (OLTC). It is the single most important piece of low-voltage instrumentation on the asset — a 10 % drop Read More
A capacitive fuel level sensor measures diesel, petrol, kerosene, or jet fuel by treating the tank as a parallel-plate capacitor and reading the change in capacitance as fuel rises and falls. It is non-mechanical, has no moving parts inside the Read More
A solid flow meter measures the mass flow of dry bulk material — cement, soybean meal, fly ash, plastic pellets, sugar, mined coal — moving through a pipe, chute, or on a belt. Unlike liquid flow, there is no single Read More
Rosemount 475 Field Communicator — Emerson-Rosemount handheld HART / FOUNDATION Fieldbus configurator. Limited original stock available. The Rosemount 475 is the handheld field communicator used worldwide to configure, commission, and troubleshoot HART and FOUNDATION Fieldbus devices — pressure transmitters, flowmeters, Read More
Updated April 24, 2026 by the Sino-Inst Engineering Team A magnetic level gauge is a mechanical indicator that reads liquid level from the outside of a vessel using a magnetic float sealed in a bypass chamber. No power, no sight Read More
Updated: April 24, 2026 — by Sino-Inst Engineering Team Molasses, honey, syrup, resin, and asphalt all share the same headache: they stop common flow meters from working. Orifice plates clog. Electromagnetic meters read zero when the fluid is non-conductive. Turbine Read More
Updated: April 23, 2026 A pressure gauge gives you a number on a dial. A how a pressure transmitter works sends a 4-20 mA signal to a control system. That single sentence drives 90% of the selection decision. The remaining Read More
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 23, 2026 Every differential pressure flow meter — orifice plate, venturi, flow nozzle, V-cone, averaging pitot — runs the same equation. Bernoulli says the velocity through a restriction goes as the square root of the pressure drop. Multiply Read More
Updated: April 22, 2026 A 6-inch (DN150) flow meter sits in a specific sweet spot — large enough to handle plant-scale cooling water, wastewater, and district heating loops, but small enough that you still have five mainstream technologies to choose Read More
