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.

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44. 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.

Programming

PROGRAMMING
The order of the ollowing programming parameters assumes the meter is set for liquid. Parameters for gaseous fluids can be found in “Gas” on page41.
OTE:N All of the following parameters appear in Extended Programming mode.
Parameters with an asterisk (*) appear in Programming mode as well.

Liquid

Select Fluid*
At the Fluid prompt, press ENTER to view the current fluid type. If the current fluid type is correct, press ENTER to advance to the next parameter. To change the fluid type, press UP or RIGHT to switch between Liquid or Gas. Press ENTER to save and advance to the Meter parameter.
Select Meter Size*
At the Meter prompt, press ENTER to display the current meter size. If the current meter size is correct, press ENTER to advance to the next parameter. To change the meter size, press UP or RIGHT to scroll to the correct meter size. Press ENTER to advance to the next parameter.
OTE:N The meter size selection refers to the bore of the meter and not the connections
size. For a listing of the Blancett turbine bore sizes, see the default K-factor table in
“Default K-Factor Values” on page42.
OTE:N In Programming mode, the monitor advances to the KFacUnit parameter.
See “Select Meter’s K-Factor Unit*” on page28.
Select Display Function
The B2900 monitor has three display settings, Flow, Grand Total and Test.

Grand Total
The Flow-GT setting forces the meter to alternate between the instantaneous flow and the grand total with roll-over counts. See Figure 10.
The grand total is the accumulation of all the fluid that has gone through the meter since the last time the grand total was cleared. This totalizer is in addition to the current total totalizer on the display and is always enabled.
In addition, the grand total screen displays the number of times the grand total has reached its maximum count (9,999,999) and rolled over to zero.

At the KFacUnt prompt, press ENTER. The display shows the current K-factor unit. If the current selection is correct, press ENTER to advance to the next parameter. To change the K-factor unit, press UP or RIGHT to scroll to the correct unit, the units should match the units that the meter was calibrated in. Press ENTER to save and advance to the
KFactor parameter.
Page 28 February 2018DSY-PM-01378-EN-06
Programming
Enter Meter’s K-Factor*
OTE:N The K-factor supplied with your meter, or calculated from calibration data, is
needed to complete this step.
At the KFactor prompt, press ENTER. The most significant digit in the K-factor flashes. If the current K-factor is correct, press ENTER to advance to the next parameter. To change the K-factor, press UP to increment the digit until it matches the meter’s first K-factor digit. Press RIGHT to advance to the next digit. Repeat this process until all K-factor digits have been entered. Press ENTER to save the K-factor and advance to the RateInt parameter.
OTE:N The number of digits available before and after the decimal point is determined
by the bore size of the flow sensor being used. The largest K-factors are associated with the smallest bore sizes. The maximum allowable K-factor is 99999.9. The minimum must be at least 1.000. If an out of range number is entered, the display flashes Limit and refuses the entry.
Select Rate Interval*
At the RateInt prompt, press ENTER. The monitor flashes the current time interval. If the current selection is correct, press ENTER to advance to the next parameter. To change to an alternate time interval, press UP or RIGHT to scroll to the required time interval. Press
ENTER to save and advance to the RateUnt parameter.
Select Flow Rate Units*
At the RateUnt prompt, press ENTER. The monitor flashes the current rate unit. If the current selection is correct, press ENTER to advance to the next parameter. To change to an alternate unit, press UP or RIGHT to scroll to the required rate unit and press ENTER to save and advance to the TotlUnt parameter.
Select Total Units of Measure*
At the TotlUnt prompt, press ENTER. The monitor flashes the current total units. If the current selection is correct, press ENTER to advance to the next parameter. To change to an alternate unit, press UP or RIGHT to scroll to the required totalization unit. Press ENTER to save and advance to the TotlMul parameter.
Select Total Multiplier*
This parameter displays the accumulated flow total in multiples of 10. For example, if the optimum totalization unit is 1000 gallons, the unit total display increments by one digit for every 1000 gallons monitored. In Run mode, at 1000 gallons the total monitor reads 1, at 3000 gallons, the total display reads 3. This feature eliminates having to look at a total, count the digits, and mentally insert commas for each 1000 multiple.
At the TotlMul prompt, press ENTER . The monitor shows the current total multiplier. If the selection is correct, press ENTER to advance to the next parameter. To change to an alternate multiplier, press UP or RIGHT to scroll to the required multiplier unit and press
ENTER to and advance to the next parameter.
OTE:N If the RateUnt or TotlUnt parameter has been set to pounds or kilograms, the
monitor advances to the Spec Gr parameter. At any other setting, the monitor advances to PulsOut in Programming mode. See “Totalizer Pulse Output*” on
page33.

Programming
Page 30 February 2018DSY-PM-01378-EN-06
Programming
Enter Specific Gravity Value*
Mass readings in the B2900 monitor are not temperature or pressure compensated so it is best to enter the specific gravity of the fluid as close to the system running temperature as possible. As liquids are essentially incompressible, pressure compensation is not necessary for liquids.
At the Spec Gr prompt, press ENTER. The most significant digit of the current specific gravity flashes. If the current specific gravity is correct, press ENTER to advance to the next parameter. To change to an alternate specific gravity, press UP to increment the flashing digit until you reach the first digit of the new specific gravity. Press RIGHT to move to the next digit. When all digits have been entered, press ENTER to save and advance to the next parameter.
OTE:N If Gas was chosen as the fluid, see “Gas” on page41 and follow the directions for
the gas parameters.
In Programming mode, the monitor advances to the PulsOut parameter, see “Totalizer Pulse
Output*” on page33.
Enter a Scale Factor
The scale factor is used to force a global span change. For example, in Run mode, the display is reading a consistent three percent below the expected values at all flow rates. Rather than changing the K-factor and linearization parameters individually, the scale factor can be set to 1.03 to correct the readings. The range of scale factors is from 0.10…5.00. The default scale factor is 1.00.
At the Scale F prompt, press ENTER. The first digit of the existing scale factor flashes. If the current selection is correct, press ENTER to advance to the next parameter. To change to an alternate scale factor, press UP to increment the display digit until it matches the first digit of the new scale factor. Press RIGHT to advance to the next digit. Repeat for all digits. Press
ENTER to save and advance to the SetTotl parameter.
OTE:N If the number you enter is out of range, the display flashes Limit and refuses the
entry.
Preset Total
The preset total parameter sets the totalizer to a predetermined amount. The preset can have seven digits up to 8,888,888.
At the SetTotl prompt, press ENTER. The monitor displays the current set total. If the set total is correct, press RIGHT to advance to the next parameter. To change the set total, press ENTER again. The first digit of the current preset total flashes. Press UP to increment the display digit until it matches the first digit of the correct preset. Press RIGHT to advance to the next digit. Repeat for all digits. Press ENTER to save and advance to the Cutoff parameter.
OTE:N If the number you enter is out of range, the display flashes Limit and refuses the
entry.
Page 31 February 2018 DSY-PM-01378-EN-06
Programming
Low Flow Cutoff
The flow cutoff shows low flow rates (that can be present when pumps are off and valves are closed) as zero flow on the flow monitor. A typical value would be about five percent of the flow sensor’s maximum flow.
Enter the low flow cutoff as an actual flow value. For example, if the maximum flow rate for the flow sensor was 100 gpm, set the low flow cutoff value to 5.0.
At the Cutoff prompt, press ENTER. The first digit of the current low flow cutoff flashes. If the current selection is correct, press ENTER to advance to the next parameter. To change the low flow cutoff, press UP to increment the display digit until it matches the first digit of the new low flow cutoff value. Press RIGHT to advance to the next digit. Repeat for all digits. Press ENTER to save and advance to the Damping parameter.
OTE:N If the number you enter is out of range, the display flashes Limit and refuses the
entry.
OTE:N If the fluid being measured is set to Gas, the monitor advances to Op Pres in
Extended Programming mode. See “Gas” on page41.
Damping Factor
The damping factor is increased to enhance the stability of the flow readings. Damping values are decreased to allow the monitor to react faster to changing values of flow. This parameter can be any value between 0…99 %, with 20 being the default.
At the Damping prompt, press ENTER. The most significant digit of the current setting flashes. If the current selection is correct, press ENTER to advance to the next parameter. To change the damping value, press UP to increment the display digit until it matches the new damping value. Press RIGHT to advance to the next digit. Press ENTER to save and advance to the PulsOut parameter.

Totalizer Pulse Output*
The PulsOut parameter can be Enabled or Disabled. When Enabled, the output generates a fixed width 30 mS duration, pulse every time the least significant digit of the totalizer increments. The amplitude of the pulse is dependent on the voltage level of the supply connected to the pulse output and is limited to a maximum 28V DC.
The B2900 monitor provides two types of totalizer pulses. The basic open drain FET output,
Figure 12, provides a ground referenced output pulse that swings between about 0.7V DC
and VCC.

Programming
Both outputs have a maximum current capacity of 100 mA and require a pullup resistor. The value of the pullup resistor is dependent on the supply voltage and the maximum current required by the load device.
Flow at 20 mA
This setting normally represents the maximum rate of the flow sensor connected to the display, but other entries are possible.
At the Fl=20mA prompt, press ENTER. The first digit of the current setting flashes. If the current setting is correct, press ENTER to advance to the next parameter. If the current setting requires a change, press UP to increment the display digit until it matches the first digit of the required maximum flow value. Press RIGHT to advance to the next digit. Repeat for all of the maximum flow at 20 mA digits. Press ENTER to save and advance to the 4-20Cal parameter.
In Programming mode, the monitor advances to the Clr G-T parameter. See “Clear Grand
Total” on page40.
4…20 mA Calibration
This setting allows the fine adjustment of the Digital to Analog Converter (DAC) that controls 4…20 mA output. If the output needs to be adjusted for any reason the 4…20 mA calibration procedure is used.
At the 4-20Cal prompt, press ENTER. The monitor displays No. If you do not need to complete the 4…20 calibration, press ENTER to advance to the Linear parameter. See
“Linearization” on page35. To complete the 4…20 calibration, press UP or RIGHT to
change the display to Yes . Press ENTER to advance to the 4mA Out parameter.
The DAC used in the B2900 monitor is an twelve bit device. The valid entries are 0…4095.

4 mA Adjustment
To set the 4 mA value, connect an ammeter in series with the loop power supply as shown in Figure 14 on page 34. The 4 mA DAC setting is typically 35…50. At the 4mA Out prompt, press UP to increase or RIGHT to decrease the current output while monitoring the ammeter. When a steady 4 mA reading is established on the ammeter, press ENTER on the monitor to save the output and advance to the 20mAOut parameter.
20 mA Adjustment
The 20 mA adjustment is performed using the same procedure as the 4 mA adjustment.
4…20 mA Test
The 4…20 mA test simulates the mA output values between 4…20 to check output tracking. At the 4-20 Test prompt the current output flashes. Press UP to increase the simulated mA output or RIGHT to decrease in increments of 1 mA. The ammeter should track the simulated mA output. If a 4…20 mA test is not necessary, press ENTER to advance to the Linear parameter.
OTE:N Pressing ENTER when the monitor is in Test mode exits the test mode and moves
on to the next programming parameter.

To increase accuracy, linearize the monitor. The linearization function accepts a maximum of ten points and requires additional calibration data from the meter being used with the monitor. Typically, calibration information can be obtained in three, five and ten points from the flow meter’s manufacturer. If linearization is not needed, press RIGHT to advance to the Modbus parameter. See “Modbus” on page36. To complete linearization, press ENTER at the Linear prompt. The meter advances to the Lin Pts parameter.
Number of Points
The Lin Pts value displays. If the number of points is set to 0, linearization is disabled. Press ENTER. The most significant digit of the number of points entry begins to flash. The first number can be 1 or 0 only. Press UP to change the first digit. Press RIGHT to move to the least significant digit.
OTE:N If the number you enter is out of range, the display flashes Limit and refuses the
entry.
Press ENTER to advance to the Freq#1 prompt.
OTE:N If the number of linear points is set to 1 the B2900 monitor assumes you are
entering the maximum frequency and coefficient. Further, the meter assumes that the implied first point is at a frequency of 0 Hz and a coefficient of 0.
Frequency
At the Freq#1 prompt, press ENTER. The first digit of the first linear point’s frequency input flashes. Press UP to increment the numerical values and RIGHT to change the position of the number being entered. When the frequency value input is complete, press ENTER to save and advance to the Coef#1 parameter.

Coefficient
The coefficient is the value applied to the nominal K-factor to correct it to the exact K-factor for that point. The coefficient is calculated by dividing the average (nominal) K-factor for that point by the actual K-factor for the flow meter.

Continue entering pairs of frequency and coefficient points until all data has been entered. Press ENTER to save and advance to the Modbus parameter.
OTE:N The frequency values must be entered in ascending order. If a lower frequency
value is entered after a higher value, the B2900 monitor flashes Limit followed by the minimum frequency value acceptable to the display.

Modbus
The Modbus output parameter can be enabled or disabled. When enabled, communications with the B2900 monitor are completed using the Modbus RTU protocol. See “Modbus Interface” on page47 for additional information.
At the Modbus prompt, press ENTER. The current state of the Modbus output is shown. If the current state is correct, press ENTER to advance to the next parameter. To change the modbus setting, press UP or RIGHT to toggle between states. When the proper state displays, press ENTER to save and advance to the BusAddr parameter.
Page 36 February 2018DSY-PM-01378-EN-06
Programming
Bus Address
If the Modbus output is enabled, you must choose a valid Modbus address. Every device communicating over the RS485 communications bus using the Modbus protocol must have a unique bus address. Address values range from 0…127 with 0 being the default.
At the BusAddr prompt, press ENTER. The first digit of the address flashes. If the current setting is correct, press ENTER to advance to the next parameter. To change the address, press UP to increment the display digit until it matches the first digit of the new bus address. Press RIGHT to advance to the next digit. Repeat for all digits of the address. Press
ENTER to save the new address and advance to the Baud parameter.
Baud
If Modbus is being used, all devices connected to the bus must have the same baud rate setting. Baud is expressed as ‘bits per second’ and defines the data transmission speed of the network. The B2900 monitor can be changed to use any of the following baud rates: 9600, 19200, 38400, 57600 and 115200. See “Modbus Interface” on page47 for additional information.
At the Baud prompt, press ENTER. The current state of the Baud rate is shown and defaults to 9600. If the current state is correct, press ENTER to advance to the next parameter. To change the baud rate setting, press UP or RIGHT to scroll through the options. When the proper state displays, press ENTER to save and advance to the SetPt1 parameter.
Set Points
Set points allow the meter to signal when a specific flow condition has been achieved. They are commonly used to indicate high or low flow conditions that need attention. The B2900 monitor has two open collector outputs controlled by the set point function.
The set point transistors have the same current limitations and setup requirements as the totalizing pulse output transistors described previously. See Figure 12 on page 33 and
Figure 13 on page 33.
Both set point one and set point two are configured using the same procedures but the hysteresis and tripping conditions are independently set for each set point output.
OTE:N In most instances, the current capacity of an open collector transistor is not
sufficient to operate old style counters that relied on relay contact closures. When used with basic counting circuits, a solid-state relay is needed.
Set Point 1
The set point is the flow value at which the output transistor changes state. It is set using the same units as the rate units.

At the SetPt 1 prompt, press ENTER. The most significant digit of the current setting flashes. If the current setting is correct, press ENTER to advance to the next parameter. To change the current setting, press RIGHT to advance to the first digit of the required set point value. Press UP to increment the digit until it matches the first number of the required set point. Repeat for all the digits the set point. Press ENTER to save the new set point and advance to the HystSP1 parameter.
Hysteresis 1
The hysteresis parameter modifies how the output transistor reacts around a set point and prevents an output from turning on and off rapidly when the programmed flow rate is at, or very near, the set point.
For example, a low flow alarm is set to activate when the flow falls below a pre-programmed point. When the flow is reduced to the set point, even small changes of flow above the set point turns the output off, disabling the alarm. Without hysteresis, if the flow rate fluctuates slightly above and below the set point, the output rapidly cycles between on and off states. See Figure 16 on page 39. The hysteresis value is set using the same units as the rate units.
At the HystSP1 prompt, press ENTER. The most significant digit of the current setting flashes. If the current setting is correct, press ENTER to advance to the next parameter. To change the current setting, press RIGHT to advance to the first digit of the new hysteresis value. Press UP to increment the digit until it matches the first number of the new hysteresis. Repeat for all the digits of the hysteresis and then press ENTER to save and advance to the TripSP1 parameter.

OTE:N Neither the set point nor the hysteresis values are checked for compatibility

Trip SP 1
The trip parameter can be set for either High or Lo. When set to High, the open collector transistor stops conducting and sends the output high when the set point is reached. The output will not go low again until the flow rate falls below the set point minus the hysteresis value. When set to Lo, the open collector transistor starts conducting and sends the output low when the set point is reached. The output will not go high again until the flow rate exceeds the set point plus the hysteresis value.
For example, if the set point is 10 gpm, the hysteresis is set to 2 gpm and the trip set point is set to High. See Figure 17. When the flow goes above 10 gpm, the OC transistor stops conducting and the output goes high. The output stays high until the flow rate drops below 8 gpm, which is the set point (10 gpm) minus the hysteresis (2 gpm).

K-Factors Explained

KFACTORS EXPLAINED
The K-factor (with regard to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid. You can think of each pulse as representing a small fraction of the totalizing unit.
An example is a K-factor of 1000 (pulses per gallon). This means that if you were counting pulses, when the count total reached 1000, you would have accumulated one gallon of liquid. Using the same reasoning, each individual pulse represents an accumulation of 1/1000 of a gallon. This relationship is independent of the time it takes to accumulate the counts.
The frequency aspect of K-factors is a little more confusing because it also involves the flow rate. The same K-factor number, with a time frame added, can be converted into a flow rate. If you accumulated 1000 counts (1 gallon) in one minute, then your flow rate would be 1 gpm. The output frequency, in Hz, is found by dividing the number of counts (1000) by the number of seconds in a minute (60) to get the output frequency.
1000 ÷ 60 = 16.6666 Hz.
If you were looking at the pulse output on a frequency counter, an output frequency of
16.666 Hz would be equal to 1 gpm. If the frequency counter registered 33.333 Hz (2 ×
16.666 Hz), then the flow rate would be 2 gpm.
Finally, if the flow rate is 2 gpm, then the accumulation of 1000 counts would take place in 30 seconds because the flow rate that the 1000 counts is accumulated, is twice as great.

Calculating K-factors

Many styles of flow meters are capable of measuring flow in a wide range of pipe sizes. Because the pipe size and volumetric units the meter will be used on varies, it may not be possible to provide a discrete K-factor. In the event that a discrete K-factor is not supplied, then the velocity range of the meter is usually provided along with a maximum frequency output.
The most basic K-factor calculation requires that an accurate flow rate and the output frequency associated with that flow rate be known.
Example 1
Known values are: Frequency = 700 Hz Flow Rate = 48 gpm
700 Hz × 60 sec = 42,000 pulses per min

650 Hz × 60 sec = 39,000 pulses per min

39,000 pulses per min
85 gpm
458.82 pulses per gallon= =
The calculation is a little more complex if the velocity is used because you first must convert the velocity into a volumetric flow rate to be able to compute a K-factor.
To convert a velocity into a volumetric flow, the velocity measurement and an accurate measurement of the inside diameter of the pipe must be known as well as one US gallon of liquid is equal to 231 cubic inches.

Known values are: Velocity = 4.3 ft/sec Inside Diameter of Pipe = 3.068 in.

What is the flow rate in gpm at 4.3 ft/sec?
0.384 gallons × 4.3 FPS × 60 sec (1 min) = 99.1 gpm
Now that the volumetric flow rate is known, all that is needed is an output frequency to determine the K-factor.

Battery Life
RS485 standards state that a daisy-chained topology is recommended with stubs being as short as possible (much shorter than the main bus length). Use a shielded twisted-pair cable no less than 24 awg for connecting devices on a RS485 network.
The B2900 monitor is rated as a 1/8 unit load device (input impedance equal to 96 kΩ). The RS485 specification states it is capable of supporting 32 standard unit loads (1 standard unit load equals 12 kΩ). In order to determine the maximum number of devices on a network, the user must identify the unit load rating of each device on the network.
The maximum common input voltage range of the B2900 monitor is –7…10V. This differs from the RS485 standard of –7…12V. To make sure this range is achieved, the RS485 ground connection must be tied together in a daisy-chained fashion. The shield of the cable used should be tied to chassis or earth ground on only one end of the network. See Figure 20 on
page 48 for an example configuration and description.
Use a termination resistor of 120 Ω at the end of the bus.
A subset of the standard Modbus commands is implemented to provide access into the data and status of the B2900 monitor. The Modbus commands and their limitations supported by the B2900 monitor can be found in Table 3 on page 48.

Modbus Register / Word Ordering

The B2900 monitor sends each byte of a 16-bit register in big-endian format. For example, the hex value ‘1234’ is sent as ‘12’ ‘34’. The B2900 monitor provides for big-endian and little-endian word ordering when a master requests data. To accomplish this, the B2900 monitor provides two register map spaces. See Table 5 on page 49 and Table 6 on page
49 for little-endian and big-endian register maps. Please note that both spaces provide
the same data.
