Insertion Magmeter Flow Sensor 2551

The Georg Fischer 2551 Magmeter is an insertion magnetic flow sensor that features no moving parts, available in corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. Material options include PP with stainless steel, PVDF with stainless steel, PVDF with Hastelloy-C, or PVDF with Titanium. Utilizing the comprehensive line of Georg Fischer installation fittings, sensor alignment and insertion depth is automatic. These versatile, simple-to-install sensors deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from DN15 to DN900 (½ to 36 inches), satisfying the requirements of many applications.

Georg Fischer 2551 Magmeters offer many output options of frequency/digital (S3L) or 4 to 20 mA which are available on both the blind and display versions. The frequency or digital (S3L) sensor output can be used with Georg Fischer's extensive line of flow instruments while the 4 to 20 mA output can be used for a direct input to PLCs, chart recorders, etc. Both the 4 to 20 mA output and digital (S3L) sensor interface is available for long distance signal transmission. An additional benefit is the empty pipe detection which features a zero flow output when the sensors are not completely wetted. Also, the frequency output is bi-directional while the 4 to 20 mA output can be set for uni- or bi-directional flow using the display or the 3-0250 USB to Digital (S3L) Configuration / Diagnostic set-up tool which connects to PCs for programming capabilities.

In addition the display version of the 2551 Magmeter is available with relays and features permanent and re-settable total values which can be seen on the display. Also, the display contains multi-languages with English, Spanish, German, French, Italian and Portuguese menu options.

Magmeter flow sensor features:
- Installs into pipe sizes: DN15 to DN900, 0.5 to 36 in
- Operating range: 0.05 to 10 m/s, 0.15 to 33 ft/s
- Max Pressure rating: PP 10.3 bar @ 25 °C, 150 psi @ 77 °F
- Power source: 4 to 20mA: 21.6 to 26.4 VDC, 22.1mA max

Overview of Paddle Wheel flow sensor 515

The Model 515 sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices include PP and PVDF make this model highly versatile and chemically compatible to many liquid process solutions. Sensors can be installed in up to DN900 (36 in.) pipes using Signet's comprehensive line of custom fittings which include tees, saddles, and weldolets, set the sensor to the proper insertion depth into the process flow. The sensors are also offered in configurations for wet-tap and intrinsically safe installation requirements.

Simple to install with time honored reliable performance, Model 515 Rotor-X paddle wheel flow sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. The output signal of the Model 515 is a sinusoidal frequency capable of driving a self-powered flowmeter (Model 5090). The wide dynamic flow range of 0.3 to 6 m/s (1 to 20 ft/s) allows the sensor to measure liquid flow rates in full pipes and can be used in low pressure systems.
