Battery Powered or Loop Powered Flow Totalizer & Ratemeter

Featuring 5 digits of rate and 8 digits of total, the BAT R/T Millennium edition (BATRT-M) is a battery powered or loop powered indicator capable of accepting magnetic pickup, DC pulse and switch closure inputs from pulse producing flowmeters. The unit can be ordered with an optional 4-20mA output. The BATRT-M uses the 4-20mA loop to provide power when this output is used.


  • Accepts Inputs From: Magnetic Pickups, Contact Closures, DC Pulses (Optically Isolated) from Pulse Producing Flowmeters
  • Displays Rate & Total Simultaneously
  • 5 Digit Rate Display, 8 Digit Totalizer Display
  • 4-20mA Analog Output Option (8 updates/sec)
  • Powered From Internal Battery, External DC Supply or 4-20 mA Output Loop
  • 20 Point Linearization (optional);
    10 Point Linearization with Data Logger option
  • Isolated Scaled Pulse Output
  • Nonvolatile Flash Memory of Setup Data




For Pulse Inputs the Count K-Factor is equal to the number of pulses per unit of measure which is determined by the flowmeter. (This Information is typically on the flowmeter calibration sheet or stamped on the flowmeter itself).

The K-Factor is Calculated as follows:

Flow Total Indication = Sum of Input Pulses / (Factor x Factor Multiplier)

The Rate Time is menu selectable: You will have the option of choosing Seconds, Minutes or Hours which adds the appropriate multiplier into the equation. See Below.

Flow Rate Indication = (Input Frequency / (Factor x Factor Multiplier) x Time Scaler

The Life Expectancy Table is listed below.

The Factory back door code for the BATRT can be obtained by calling the factory or send an email.

The Operating Temperature of the BATR/T is listed below:

-4°F (-20°C) to + 158°F (70°C)
Extended Temp: -22°F (-30°C) to + 158°F (70°C)

0.01% Reading, ±1 count
Temperature Drift: 50 ppm/°C Worst Case

Yes, the BATR/T front panel is NEMA 4X rated. This rating is also comparable to the European standard IP65.

The user can view the Rate and Total of flow on the Two Line Display. The Rate is shown on the top line and the Total is shown on the bottom line of the display.

The BATR/T has a battery backed memory and is capable of storing program and count data for the life of the battery. The unit also has a “BAT” warning that will activate on the display when the battery reaches the end of its useful life.

The flow total may be cleared by the front panel or by a contact closure on the remote reset terminal to circuit common. To reset the unit from the front panel, the following sequence is required:

Below you will find typical wiring diagrams to help you wire a flowmeter to the BATR/T
