Section 6 – Optional Wireless Transmitter Operation

6.1 Introduction

Compared to a wired connection, a wireless meter provides much simpler 

installation. Based on the physical principle of the propagation of radio 

waves, certain basic conditions should be observed. The following simple 

recommendations are provided to ensure proper installation and correct 

operation of your wireless meter.

6.2 RF Communication Basics

Your wireless transmitter sends wireless transmissions to a receiver. The receiver 

checks the incoming data for accuracy and processes this data for use by the 

measurement software on your PC. Radio signals are electromagnetic waves, 

hence the signal becomes weaker the further it travels. While radio waves can 

penetrate some solid materials like a wall, they are dampened more than when a 

direct line-of-sight between the transmitting and receiving antennas exists.

6.3 Basic System Overview

A basic wireless system is comprised of only two main components; a signal 

conditioner with a built-in battery powered 2.4GHz radio transmitter, and a USB 

powered 2.4GHz radio receiver. 
Installation
When installing your meter it is important to position the unit in such a way as 

to optimize the antenna location within what’s known as the “Fresnel Zone”.
The Fresnel Zone can be thought of as a football-shaped invisible tunnel between 

two locations that provides a path for RF signals between your meter and your 

receiver.

Figure 6-1.  Fresnel Zone

In order to achieve maximum range, the football-shaped path in which radio 

waves travel must be free of all obstructions. Obstacles in the path (especially 

metal) will decrease the communication range between your meter and receiver.
