Wireless Pulse Counter - Single Input
General Description
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
specifcations. 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.

Power Options
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is
also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered
by a standard 3.0–3.6 V power supply. The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted
operation in the event of line power outage. Power options must be selected at time of purchase, as the internal hardware of the sensor
must be changed to support the selected power requirements.

gas, etc.
•
Volatile or flammable gas
• Dusty conditions
• Low-pressure or high-pressure environments
• Wet or excessively humid locations
• Places with salt water, oils chemical liquids or organic solvents
• Where there are excessively strong vibrations
