QC0144 Optical Pulse Transmitter Installation Manual

1. Introduction

The Optical Pulse Transmitter is a battery powered wireless transmitter capable of capturing pulse
information from metering equipment fitted with a visible flashing pulse output. This sensor uses a

special reader head to count the number of flashes made by the ‘Impulse’ LED found on many

domestic and commercial electricity meters. Since the number of flashes relates to a certain
amount of electricity consumed it can easily be converted into kWh. This sensor uses a modified
version of the pulse sensor. The data collected by the additional wireless gateway can be viewed on
the Realtime Online platform.

Features

 A variety of available radio frequency options
 Small footprint
 Automatic data collection and transmission
 Wireless, range of up to 15km line of sight
 Battery powered with up to 3-year battery life
 None invasive and rapid installation with no cabling required

Technical information

 Operating frequency 868MHz (Other frequencies available 915 MHz)
 Measurement Accuracy in line with equipment it is connected to.
 Operating range up to 15km
 Suitable to monitor any device with a visible pulse output
 Storage Conditions: 0 °C to +50 °C
 Relative Humidity: 25% to 95%
 Operating Temperature: 0 °C to 40 °C
 Mains powered optional

Applications

 Energy Monitoring
 Bill validation
 Sub-metering

Installations where use of CT/VT’s is not practical.

2. Installation

This sensor is supplied with a special sensor head that must be placed exactly over the flashing LED
using the self-adhesive backing.

The LED also needs to be close to or flush with the utility meter case for it to be seen more
accurately, if the light is recessed inside the meter the pulse light may not be seen.

Note that there is a guide mark in the shape of a cross on
the sensor to aid positioning.

The sensor cannot be re-positioned once placed, so ensure
that it is correctly positioned when attaching to the meter.

These sensors are known to perform badly if there is a large
amount of ambient light, so it is preferable to install these
inside a closed cabinet with the transmitter part outside.

Pulse Ranges

0 – 5,000 pulses per hour

Update Rate

Every 7 ½ Mins (8 times per hour).

Most Realtime-Online™ sensors have a unique mounting clip on the battery compartment
which allows the sensor to be installed:

Mounted with screws through the mounting clip.
