Introduction

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 re­configured in the field. Finally, you can choose between simultaneously showing rate and total, or alternating between rate and grand total.

Scope of This Manual

SCOPE OF THIS MANUAL
This manual is intended to help you get the B2900 flow monitor up and running quickly.
MPORTANTI
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.
OTE:N 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 B2900 Monitor to a Frequency Output Device

The B2900 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 B2900 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.
OTE:N 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 B2900 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 B2900 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.

If the monitor is a replacement, the turbine’s K-factor changed or the monitor is used with some other pulse generating device, you must program it.

Programming Using Frequency Output Turbine Flow Meters

Each Blancett turbine flow meter is shipped with either a K-factor value or frequency data. If frequency data is provided, the data must be converted to a K-factor before programming the monitor. K-factor information, when supplied, can usually be found on the neck of the flow meter or stamped on the flow meter body. The K-factor represents the number of pulses per unit of volume. See “K-Factors Explained” on page40. The K-factor is required to program the monitor.

Enter Programming Mode

To access the Programming mode, momentarily press and then release MENU. The monitor displays Fluid. To access the Extended Programming mode, press and hold MENU until Fluid is displayed. To return to Run mode, press MENU.
