  • Page 28 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�...
  • Page 29 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�...
  • Page 30 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 31 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�...

  • Page 41: 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 42 K-Factors Explained Example 2 Known values are: Full Scale Flow Rate 85 gpm Full Scale Output Frequency = 650 Hz 650 Hz × 60 sec = 39,000 pulses per min 39,000 pulses per min K-factor 458.82 pulses per gallon 85 gpm 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�...
