The Signet 2551 display magmeter has no moving parts which lets the unit measure flows with high particle, solids, or fiber content without wear or fouling.
An integral 2 16-character dotmatrix LCD provides local readings of flow rate, permanent total flow, and a resettable flow total in one of six userselectable languages. Mechanical SPDT or solid-state relays for alarm indication or control of valves or pumps are options.
The 2551 detects and indicates empty pipe conditions with a zero-flow signal output. Output options include frequency, digital, or 4 to 20 mA. The frequency output handles bidirectional sensing while the 4 to 20-mA output is settable for single or bidirectional flow. Housings available include PVDF (polyvinylidene fluoride), Hastelloy C wetted part configurations, PP (polypropylene), and PVDF body with stainless-steel electrodes. The unit mounts in pipe sizes ranging from 0.5 to 8 in. (DN15 to DN200) with standard installation fittings. Performance characteristics include a dynamic flow range of 0.15 to 33 fps (0.05 to 10 m/sec) with a linearity of ±1% and repeatability of ±0.5% of reading.
