Series 340 BN/MB Transmitter

Flow Sensor Section

Figure 23:  Pulse or Sine

For most Badger Meter sensors the sensor type is “Pulse”, and the “K” and “Offset” values can be found in the respective Flow 

Sensor Manual. 

“Sine” is used for zero-crossing flow sensors (some turbine meters, etc.)

Several flow rate and flow total units of measure can be selected from the pull-down menu.

Temperature Sensor Section

Figure 24:  Sensor Attributes

First choose the sensor type ( 10K Thermistor, 100 Ohm RTD, or 1K RTD).

The calculation mode has three selections.

Initially, it is best to choose “Absolute.” In this mode the Energy Rate and Total will be calculated as a positive value regardless 

of the direction of energy flow.

In the T1>T2 Mode, energy will only be calculated if the T1 sensor is warmer than the T2 sensor.

If T1 is cooler than T2, the energy rate will remain at 0.0, and the energy total will not increase.

In the T1<T2 Mode, energy will only be calculated if the T1 sensor is cooler than the T2 sensor.

The T1= and T2= are simply for reference to indicate the current temperature readings.

This is useful in using the zeroing Feature explained on page 19.
