Blancett B2800 Flow Monitor

The B2800 is a technologically advanced flow monitor designed to be comprehensive, user-friendly, flexible and cost efficient. This microprocessor-based display comes pre-calibrated by the factory when purchased with a Blancett turbine flow meter, or it can easily be configured in the field. The user may choose between the Standard model which is programmed in seven simple steps and the Advanced model which provides additional programming options.

The B2800 is offered in six mounting configurations: meter, remote, swivel and hand-held, as well as a panel version and explosion-proof display allowing for flexible installation. The B2800, when paired with a rugged, reliable Blancett turbine flow meter, will provide dependable and accurate flow information for many years to come. The B2800 may also be used with almost any flow sensor that outputs a low-amplitude AC signal.

B2800 Features:

Displays rate and/or total
Large 8 digit by 3/4" display for easy viewing (meter, remote and swivel mount plus hand-held versions)
Battery-powered unit utilizes one "D" size 1.5 volt alkaline battery for 3-1/2 years of service Loop-powered, 4-20 mA version available
User friendly front panel programming
Ten point linearization (Advanced model only)
NEMA 4 enclosure suitable for outdoor monitoring (meter, remote and swivel mount)
Intrinsically safe (meter, remote and swivel mount) Microprocessor-based, low power consumption
Six mounting options: meter, remote, swivel, hand-held, panel or explosion-proof
Standard model displays in four selectable units of measure: GPM/gallons, LPM/liters, M3PD/cubic meters, or BPD/barrels
Advanced model offers eleven selectable units of measure: gallons, oil barrels, liters, cubic meters, Mgal, cubic ft, Mliters, acre ft, liquid barrels, Ibs, or kgs
Advanced model allows selection of time intervals for rate measurement in either day, hour, minute, or second

B2800 Operating Principle:

The B2800 flow monitor accepts a low-level frequency input, such as the input from a Blancett turbine meter, to calculate flow rate and total. These calculations are then displayed in user selected units of measurement. All B2800 flow monitors come pre-calibrated from the factory if ordered with a Blancett flow meter. However, they can be easily reconfigured in the field. The B2800 is available in a battery-powered or loop-powered version. The battery version utilizes one "D,° size, 1.5 volt alkaline battery that provides up to 3-1/2 years of service.

The loop-powered B2800 offers a 2-wire 4-20 mA output for electronic integration. The meter mount, remote, swivel and hand-held monitors are equipped with a large 8 digit by 3/4" numerical LCD making extended range viewing practical. The second 8 character by 3/8" alphanumeric display provides for selectable units viewing in run mode and prompts variables in programming mode. Additionally, the user can choose between displaying rate, total or alternating between both rate and total.
