The TORNADO109 Depth Watcher system is a portable device that runs on batteries or external power and has an LCD display that an operator can use to see the actual depth, speed, and tension during a slickline job. The system can be set up using a very simple menu or by connecting to a PC. It can be operated on a stand alone mode (Memory) or on a real time mode (SRO) with the use of a PC to display depth, speed, tension and two additional channels.
It is also equipped with three additional 4-20mA channels for measuring other wellhead parameters. This device uses a NEMA 4 type of enclosure constructed for either indoor or outdoor use to provide protection to personnel against incidental contact with the device and to the device against falling dirt, rain, snow, etc.
Applications:
• Slickline Depth Recorder
• Coiled Tubing Depth Recorder with customized adapter
• Wireline Depth Recorder
