INTRODUCTION
The BP2900 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 Pembina Controls flow sensors, this monitor can be used with almost any flow
sensor producing a low amplitude AC output or contact closure signal
Figure 1: BP2900 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 BP2900 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

SCOPE OF THIS MANUAL
This manual is intended to help you get the BP2900 flow monitor up and running quickly
IMPORTANT
Read this manual carefully before attempting any installation or operation. Keep the manual
accessible for future reference.
UNPACKING AND INSPECTION
Upon opening the shipping container, visually inspect the product and applicable
accessories for any physical damage such as scratches, loose or broken parts, or any other
sign of damage that may have occurred during shipment
NOTE: If damage is found, request an inspection by the carrier’s agent within 48 hours of
delivery and file a claim with the carrier. A claim for equipment damage in transit
is the sole responsibility of the purchaser.

INSTALLATION
Connecting the BP2900 Monitor to a Frequency Output Device
The BP2900 monitor has two jumpers for setting the type of signal and the minimum
amplitude of the signal that it accepts First, establish the type of output provided by the
flow sensor The outputs almost always fall into one of two types
• Type 1 is the unaltered frequency signal coming from an un-amplified magnetic
pickup. This signal is normally a sine wave in appearance, and the amplitude of the
waveform varies with the flow. Small turbines have comparatively small rotating
masses so they produce a smaller amplitude waveform and higher frequencies than
larger turbine sensors.
• Type 2 is the frequency signal from the transducer is amplified, wave shaped or both
to produce a waveform of a specified type and amplitude. Most amplified transducers
output a square wave shape at one of many standard amplitudes. For example, a
popular amplified output is a 10V DC square wave.
If the flow sensors output signal is type 1, you must also determine the minimum
amplitude of the frequency output The BP2900 monitor has a high or low signal sensitivity
setting Use the high signal sensitivity (30 mV) with low amplitude (usually small) turbine
flow sensors Use the low signal sensitivity setting (60 mV) for larger turbines and amplified
transducers See Figure 2 on page 8
NOTE: Use the high signal sensitivity setting where the minimum signal amplitude
is below 60 mV. Setting the sensitivity higher than necessary may allow noise
interference.

When the type of waveform and input signal level (amplitude) are determined, set the
jumpers on the BP2900 monitor circuit board
For typical variable reluctance magnetic pickups, set the waveform selection jumper
for Mag Determine the setting for the input level by looking at the magnetic pickup
specifications If the minimum amplitude at the minimum rated flow is greater than 60 mV,
use the low signal sensitivity jumper position See Figure 2
If the minimum signal level is below 60 mV, use the high signal sensitivity jumper position

POWER CONNECTIONS
Standard
The power supply used in the BP2900 monitor is an internal lithium 3.6V DC D cell that
powers the monitor for about six years when no outputs are used The monitor can also
get power from a 4…20 mA current loop See Figure 5 If the current loop is used, a
sensing circuit within the monitor detects the presence of the current loop and
disconnects the battery from the circuit
