7 Chapter 2 Installation The components in Luna iMonitoring’s Intelligent Wireless Sensor Suite are easy to install using simple tools. The installation guidelines in this manual outline the steps for selecting the proper site for the device, and for handling, mounting and activating the device. Site Selection for WEMS Components The iTLM-1 and iWPM-T sensor modules mount directly onto oil and gas tanks, pipelines, and wellheads in the field.
8 Chapter 2 Installation 2 2 2 2 2 2 2 2 2 2 2 2 2 2 • • With a direct line-of-sight, the WEMS components communicate up to 2500 feet. However, without a direct line-of-sight, this distance decreases. Place the iCCU as high as possible to improve signal transmission and reception. Avoid placing sensor modules and iCCUs near electrical equipment or large metal objects.
Oil & Gas Wireless Enabled Monitoring System 9 Installer’s Guide Figure 2-1. Typical Label Found on all Luna iMonitoring Radio-linked Devices. Guidelines Concerning Solar Panels All of Luna iMonitoring’s sensor modules and iCCUs employ a single, solar-assisted battery for power. Properly orienting the solar panels on the WEMS component achieves a maximum battery life of more than two years. Place the component in a non-shaded area with the solar panels facing toward the sun.
10 Chapter 2 Installation 2 2 2 2 2 2 2 2 2 2 2 2 2 2 Guidelines Concerning iTLM-1 Mounting The iTLM-1 uses Ultrasonic Sensing Technology to provide tank fluid level measurements. The sensor projects an ultrasonic beam at the surface of the liquid in a tank. The beam reflects off the liquid’s surface back to the sensor. The iTLM-1 acquires the raw measurement and then compensates for the effects of temperature on the raw data.
Oil & Gas Wireless Enabled Monitoring System 11 Installer’s Guide Pre-installation iTLM-1 Depth Calibration Before installing the iTLM-1 sensor device on a tank, perform the iTLM-1 depth calibration procedure.
