The online DP density meter measures liquid density from a hydrostatic pressure difference between two fixed points in the process. Range is 0.5 – 2.5 g/cc (500 – 2500 kg/m³), accuracy ±0.5% of reading, output 4–20 mA + HART. It Read More
Updated April 20, 2026 by Sino-Inst Engineering Team Choosing an ammonia flow meter starts with one question: is the NH3 liquid, gas, or switching between both? Each phase demands a different meter technology. Anhydrous liquid ammonia pressurized to 10 bar Read More
Updated April 20, 2026 by Sino-Inst Engineering Team A 4–20 mA pressure transmitter with “no output” looks like a dead sensor, but it almost never is. In our field records, 80% of no-output calls trace to five things: wrong wiring Read More
The tuning fork density meter is an inline vibrating-fork sensor that measures liquid density from 0 to 2500 kg/m³ with ±1 kg/m³ accuracy. The fork tines sit directly in the process line — their resonant frequency shifts with the density Read More
SI-100 Rigid Probe Magnetostrictive Level Transmitter Stainless probe, 0.2 to 6 m measuring range, ±0.1 mm accuracy, 4-20 mA / HART / Modbus, ATEX option. Built for atmospheric and pressurized tanks where you need a rigid stem instead of a Read More
Updated on April 18, 2026 — The Verabar flow meter is an averaging pitot tube that measures flow by sensing differential pressure across multiple ports in a pipe cross-section. It handles pipe sizes from DN50 to DN6000, covers gas, steam, Read More
Updated Apr 17, 2026 — Differential pressure (DP) flow measurement relies on a flow element — a restriction in the pipe that creates a pressure drop proportional to flow rate. But not all flow elements perform equally. Each type trades Read More
Updated: April 15, 2026 A metal tube flow meter is a variable-area (VA) rotameter built with a stainless steel measuring tube instead of glass. A float inside the tube rises to a height proportional to the flow rate, and a 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
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
