Introduction

The ALTA Wireless Pulse Counter can be connected to the pulse output of a system (water meter, electricity meter, etc.) to count the number of pulse triggers within a given time range.

• Count the number of pulses within a given time range, or continuously accumulate pulses.
• Three filter settings available: no filter, 4Hz filter, and 40Hz filter.
• Capable of counting both passive (open/close switch) and active (up to +15VDC) pulses.
• Capable of counting rising edge, falling edge, or both edges of a pulse.

The ALTA Wireless Pulse Counter is an electronic counter capable of counting passive (open/close switch) or active (up to +15VDC) pulses. The counter includes three software-configurable low-pass filter settings (no filter, 40Hz filter, or 4Hz filter). The pulse counter filters out pulses with a pulse width greater than the value specified in the technical specifications. For example, if the 4Hz filter is set, the pulse counter will count pulses with a width greater than 250ms; pulses with a width less than 250ms will be fully or partially filtered (refer to the specification sheet for detailed filter information). The sensor can be configured to send alerts through the iMonnit online sensor monitoring and notification system when a given number of pulses is reached within a set time range. iMonnit system alerts are delivered in real time via SMS or email.
