Page 6: General Information
General Information The NuFlo TMP-100 Turbine Meter Pulse Divider Circuit is a solid-state electronic instrument designed for use with a NuFlo turbine flowmeter. The TMP-100 provides a pulse output in the form of two dry contacts from a two-pole relay, single-pole relay or an opto- isolated open collector transistor output. -
Page 7: Installation
Installation Mounting The TMP-100 circuit board is designed to be mounted with screw-mounted standoffs or push-on style circuit board supports. Mount the TMP-100 in a clean, dry location suitable for electronic circuit assemblies where it will not be subjected to extreme operating temperatures (below -20ºF or above +140ºF). The mounting location should ensure easy access to the terminal strip, divisor switches, and pulse duration adjustment. -
Page 8: Wiring
Wiring All field wiring is attached to the instrument on the 16-position terminal strip near the edge of the circuit board (Figure 2). The power requirement for the unit is 10 to 28 VDC. 10 to 28 VDC power Turbine meter magnetic pickup Turbine meter frequency out... -
Page 9: Calibration
Installations requiring a turbine meter frequency output are labeled A&S and COM. These terminals provide a 0- to 5-V square-wave output, representing the turbine meter frequency. A load with a resistance 250K ohm or larger may be connected to these terminals. The shield wire must be connected to the COM terminal. - Page 10 Determining the Divisor The divisor is determined by the flowmeter calibration factor and the conversion factor for the desired units of calibration. Example: A customer has a 2-in. turbine meter with a calibration factor of 55.2 pulses per gallon. The desired unit of registration is barrels.

Page 11: Pulse Direction And Duration Adjustment
Switch SW1 positions 1 through 10 and switch SW2 positions 1 through 9 are used to select a divisor. Switch SW2, position 10, is used for pulse direction. This function is described in the Pulse Direction and Duration section. Determining Switch Position To determine which switches should be closed, perform the following steps: 1. -
Page 12: Input Signal Sensitivity Adjustment
Adjusting the pulse duration requires an oscilloscope, a power supply, and a signal generator. To adjust the pulse duration, perform the following steps: 1. Connect the power supply to the POWER IN terminals as shown in Figure 2. 2. Connect the signal generator in place of the turbine meter on the TM IN terminals. 3. -
