Blancett B3150 — Explosion-Proof Flow Monitor

Product Overview

The Blancett B3150 is the explosion-proof member of the Blancett electronics line — a field readout that brings rate and total right to a meter sitting in a classified zone. The die-cast enclosure carries the explosion-proof rating (ATEX / IECEx / FM / CSA c-us, Class I Div 1); it threads to the meter on a 1 in. NPT hub, and where the location is hazardous the monitor goes onto an explosion-proof meter with meter-mount kit B280-757. Setup and reading happen from the front: three infra-red keys work through the glass, so the enclosure never has to come open, and the screen carries an alphanumeric readout with a speedometer bar graph behind a bright LED backlight. A 16-point linearization curve trims the meter signal for accuracy and the totals can read in volumetric or mass units. HART 7 ships integrated for loop reading and configuration, with Modbus RS-485 available as an option; analog hosts get a galvanically isolated 4–20 mA signal scaled to rate, plus a passive pulse for total. Power is flexible — run it off a 9–27V DC loop, or stand it alone on a long-life lithium battery (roughly three years) at sites with no field power — and it reads Blancett turbine and positive-displacement meters.
