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
Upstream and Downstream Straight Pipe Requirements for Flow Meters Updated April 2026 — By Sino-Inst Engineering Team Straight pipe length is one of the most overlooked variables in flow meter accuracy. The 10D upstream, 5D downstream rule appears in nearly Read More
Updated on April 18, 2026 — Chilled water flow measurement drives HVAC energy billing, chiller plant optimization, and BTU tracking. Picking the wrong meter type wastes money on installation or produces readings that drift by 5-10% under part-load conditions. This Read More
Updated on April 18, 2026 — Most DP transmitter measurement errors trace back to installation mistakes — not faulty hardware. Incorrect mounting orientation, improperly sloped impulse lines, or a skipped commissioning step can introduce errors that persist for years. This Read More
Updated on April 17, 2026 — Most flow meters can be installed vertically, but accuracy depends on matching flow direction to meter type. Get it wrong, and you lose 2–5% accuracy or worse. This guide covers vertical pipe flow measurement 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 Apr 17, 2026 — A pressure transmitter is only as accurate as its installation. Get the mounting position wrong, run sloppy impulse lines, or skip the root valve, and you will chase phantom readings for months. This guide walks 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
