Venturi Tube Principle

flow element used to create a pressure change by accelerating a fluid stream is the venturi tube: a pipe purposefully narrowed to create a region of low pressure. As shown previously, venturi tubes are not the only structure capable of producing a flow-dependent pressure drop. You should keep this in mind as we proceed to derive equations relating… Read More »

Servo Gauge Tank Level Measurement

Tank gauging system is based on the principle of displacement measurement. A small displacer is accurately positioned in the liquid medium using a servo motor. The displacer is suspended on a measuring wire that is wound onto a finely grooved drum housing within the instrument. The drum is driven via coupling magnets, which are completely separated by the drum housing.… Read More »

Leakage detectioon system for cooling tower

If water enters an oxygen lance from a leak in the cooling system, the results can be  catastrophic. Why take the risk, when simple means exist to avoid it. Endress+Hauser’s highly accurate leakage detection system, designed to IEC 61511 and EN ISO 13849-1, detects the slightest signs of a leak, so that action can be… Read More »
