Differential pressure is the hardest-working measurement in the plant. It meters flow through orifice plates and pitot tubes, watches filters load up, measures tank level from the bottom up, and derives density. And it's the measurement most people under-specify — because a DP error doesn't just add, it multiplies. Here's why: flow from differential pressure follows a square-root relationship. A 1% error in DP becomes roughly a 0.5% error in flow — but more importantly, at low flows …

Ask a plant engineer what kills flow meters, and you'll hear the same story: the turbine that seized after six months of slurry, the paddle wheel chewed up by chemical dosing, the meter that "reads fine" until the batch comes out wrong. Mechanical flow measurement has moving parts, and moving parts in process service are a maintenance contract you never signed. The Aplisens PEM-500 sidesteps the whole problem. It's a mag meter — no rotor, no paddle, no bearings. Nothing touches the process …

Pressure is the most measured variable in the plant — and the most taken for granted. A pressure transmitter that's "close enough" drives a control valve that's always hunting, a batch that's always slightly off, or a safety system working with numbers it can't trust. The Aplisens PCE-28.SMART exists for the engineer who's done accepting "close enough." What ±0.1% Actually Means On a 10 bar range, ±0.1% is ±10 millibar — about the pressure of a strong breath. Tha …

Every plant has instruments nobody can read without a pilgrimage — the transmitter behind the vessel, the one at the top of the pipe rack, the one whose reading you need right now while you're standing next to the pump. The Aplisens APC-2000ALW is built for exactly those spots: a smart pressure transmitter with a backlit local display and configuration keys, so the reading and the controls are where the work happens. Why a Display Is Worth Paying For A display looks like a luxury until you …

Aplisens S.A. is one of Europe's leading manufacturers of process instrumentation — pressure, flow, level, and temperature measurement built in Warsaw, Poland, and trusted in plants around the world. At CPS Calibrations we stock their line, and one instrument gets asked about more than the rest: the PEM-1000 electromagnetic flowmeter — the mag meter. Here's what makes it worth a look, plus the other Aplisens highlights we carry. The Star: PEM-1000 Electromagnetic Flowmeter (Mag Meter …
