The Signet 2551 Display Magmeter, an insertion style electro-magnetic flow sensor, 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 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. The display indicates flow rate, permanent flow total and resettable flow total in one of six user-selectable languages on an easy-to-read 2 x 16 character dot matrix LCD format. 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. All versions of the 2551 Magmeter (including the blind unit) are now available in a PVDF (polyvinylidene fluoride) and Hastelloy C wetted part configuration.
