Wireless Pulse Counter - Single Input

Description Features Configuration Application

The ALTA wireless pulse counter can be connected to the pulse output of a system (water meter, power meter, etc.) to count the number of actuations within a given time frame.

• Counts the number of pulses in given time frame, or aggregates pulses in an ongoing accumulation.

• 3 filter settings: No filter, 4 Hz filter, and 40 Hz filter.

• Capable of counting passive (open/closed switch) and active (Up to +15 VDC) pulses.

• Capable of counting the positive edge, negative edge, or both edges of a pulse.

 

Principle of Operation

The ALTA wireless pulse counter is an electronic counter capable of counting passive(open/closed switch) or active (Up to +15 VDC) pulses. The counter includes 3 software configurable low pass filter settings (No filter, 40 Hz filter, or 4 Hz filter). The pulse counter filters pulses with pulse widths greater than those designated in the technical specifications. For example, if the 4Hz filter is set, the pulse counter will count a pulse if the pulse width is longer than 250 ms, if the pulse width is shorter than 250 ms it will be completely or partially filtered (See the Technical Specification table for detailed filtering information).

The sensor can be set to send an alert through the iMonnit Online Sensor Monitoring and Notification System when a given number of pulses have been reached within a set time frame. Alerts from the iMonnit system are sent as they happen (in real time) via SMS text or email.

•   Wireless range of 1,200+ feet through 12+ walls *

•   Frequency-Hopping Spread Spectrum (FHSS)

•   Improved interference immunity

•   Improved power management for longer battery life **(12+ years on AA batteries)

•   Encrypt-RF® Security (Diffie-Hellman Key Exchange+AES-128 CBC for sensor data messages)

•   Onboard data memory stores up to 512 readings per sensor:

- 10-minute heartbeats = 3.5 days

- 2-hour heartbeats = 42 days

•   Over-the-air updates (future proof)

•   Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email

*Actual range may vary depending on environment.

**Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
