GF Signet 3-2551-P0-42 Magmeter | 4-20mA Flow Sensor

Georg Fischer Signet 3-2551-P0-42 Magmeter

The GF Signet 3-2551 is an electromagnetic flow sensor that works well with liquids that conduct electricity. The sensor can accurately measure flow velocity even in fluids that have a lot of solids or debris in them, thanks to Faraday’s Law of Induction. Because it is so well made, it will last a long time in chemical processing, water treatment, and marine ballast systems.

The GF Signet 2551 Magmeter is the best electromagnetic flow sensor for harsh, corrosive, or high-particulate environments from an engineering point of view. This magmeter doesn’t have any moving parts, so it won’t wear out as quickly as mechanical paddlewheel sensors. This means that maintenance intervals are much shorter in tough marine and industrial piping systems.

The 3-2551-P0-42 model has a polypropylene body and 316L stainless steel electrodes. It can output 4 to 20 mA, which makes it easy to use with PLC and SCADA monitoring systems.

Technical Specifications

NdMarineTech Expert’s Tips:

-> Placement is important: Make sure there is at least 10 pipe diameters of straight run before the sensor and 5 pipe diameters after it to get a fully developed laminar flow profile.

-> Don’t put the sensor at the highest point of a piping system. This will create air pockets. Air bubbles can make the sensor read wrong or set off alarms for empty pipes.

-> Orientation: If the fluid has sediment in it, put the sensor in a horizontal position at a 45-degree angle. Stay away from the bottom, where silt settles, and the top, where air gets trapped.

-> Conductivity Check: Make sure that the fluid you are using has a conductivity of at least 20 μS/cm. This technology can’t measure deionized water or ultra-pure water.
