INTRODUCTION
The B2900 flow monitor incorporates state-of-the-art, digital signal processing technology,
designed to provide exceptional flexibility at a very affordable price� Though designed
for use with Blancett flow sensors, this monitor can be used with almost any flow sensor
producing a low amplitude AC output or contact closure signal�
Figure 1: B2900 Flow monitor (NEMA 4X)
This monitor can accept low-level frequency input signals typically found in turbine flow
sensors� The output signal for these types of sensors is a frequency proportional to the rate
of flow� The B2900 monitor uses the frequency information to calculate flow rate and total
flow� Through the use of the programming buttons, you can select rate units, total units
and unit time intervals among other functions� If required, the monitor can easily be re-
configured in the field� Finally, you can choose between simultaneously showing rate and
total, or alternating between rate and grand total�
