  • Page 5: Introduction

    . All BK2900 flow monitors come pre-configured from the factory, when ordered with a Kimray flow sensor . 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 .

  • Page 6: Scope Of This Manual

    Scope of This Manual SCOPE OF THIS MANUAL This manual is intended to help you get the BK2900 flow monitor up and running quickly . MPORTANT 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 .

  • Page 7: Installation

    Installation INSTALLATION Connecting the BK2900 Monitor to a Frequency Output Device The BK2900 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 . •...

  • Page 11: Modes Of Operation

    Diagnostic tool to show input frequency and totalizer counts If your monitor was ordered with a Kimray flow meter, the two components ship from the factory configured as a set . 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 .

  • Page 12: Programming

    . OTEE: The meter size selection refers to the bore of the meter and not the connections size . For a listing of the Kimray turbine bore sizes, see the default K-factor table in Default K-Factor Values on page 22 .
  • Page 13 Programming Grand Total The Flow-GT setting forces the meter to alternate between the instantaneous flow and the grand total with roll-over counts . 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 .
  • Page 14 Programming 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 .
  • Page 15 Programming 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 .
  • Page 16 Programming 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 .
  • Page 17 Programming 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 .
  • Page 18 Programming Linearization 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 .
  • Page 19 Programming Modbus The Modbus output parameter can be enabled or disabled . When enabled, communications with the BK2900 monitor are completed using the Modbus RTU protocol . See Modbus Interface on page 31 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 .
  • Page 20 Programming 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 .

    Programming Clear Grand Total At the Clr G-T prompt, press ENTER . The monitor displays No on the screen . To clear the grand total, press UP or RIGHT to change from No to Yes . Press ENTER to save and advance to the Passwd parameter . The totalizer can also be reset using a hardware reset, as shown in the following diagrams or by pressing MENU and ENTER simultaneously .

  • Page 28: K-Factors Explained

    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) .

  • Page 32: Modbus Register / Word Ordering

    Modbus Interface Modbus Register / Word Ordering The BK2900 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 BK2900 monitor provides for big-endian and little-endian word ordering when a master requests data . To accomplish this, the BK2900 monitor provides two register map spaces .
