New 2551 Display Magmeter Features Empty Pipe Detection and Bi-Directional Flow Capabilities

Georg Fischer Signet is proud to introduce the 2551 Display Magmeter, an insertion style electro-magnetic flow sensor, that provides increased functionality with built-in display, empty pipe detection and bi-directional flow capabilities. These sophisticated features, combined with its availability in PVDF/Hastelloy-C, PP, PVDF and stainless steel wetted parts, enable the unit to meet a wide range of application needs. With no moving parts to wear or foul, the 2551 accurately measures flow in fluids containing a high content of particles, solids and fibers, making it an excellent choice for applications with dirty fluids.

The new display unit provides a convenient, all-in-one, integral device that allows local measurement readings, thus reducing the number of separate components required at the sensing point. For further flexibility, the unit can be ordered with optional mechanical SPDT or solid state relays for alarm indication or control of valves or pumps.

The 2551 Display also provides an extremely stable output signal, even when exposed to air, and can detect and indicate an empty pipe condition. An empty pipe is detected by sensing when the electrodes are not completely wetted and indicates the condition with a zero flow signal output. This feature eliminates the need to perform special plumbing to keep the sensor wet at all times, or the need to re-pipe or re-mount the sensor in another location when fluid is emptied from the pipe.

For applications where bi-directional flow measurement is required, as in many filter applications, the display unit's capability to measure flow in both directions becomes particularly important. Frequency output is bi-directional, while the 4 to 20mA output can be set for single or bi-directional flow.

All versions of the 2551 Magmeter (including the blind unit introduced earlier this year) are available in PVDF and Hastelloy-C wetted part configurations. This material combination broadens the unit's chemical compatability range to include a variety of highly corrosive applications. Other materials choices include either PP or PVDF body with stainless steel electrodes.
