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.

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.
