Page 75: Conclusion
5.3.1 Overview The Hydran M2-X is installed on a single transformer valve. The valve should have no internal restrictions, recommended to be installed full-bore gate valve or ball valve. GE recommends that all cables carrying; Power, Communications, analogue inputs and outputs, be run in either rigid steel conduit or flexible steel liquid tight armored conduit.
Page 76: Tools And Materials Required
5.3.2 Tools and Materials Required In addition to the supplied tools and accessories (see the shipping list in Section 5.1.2), you will need the following ones to install the Hydran M2-X (see Figure 5-2): • 3-mm (1/8-in) flat-blade screwdriver. • #2 Phillips screw driver.
Page 77 Our tests have indicated that if a 1-in pipe is used to install the Hydran M2-X to a distance exceeding 63 mm (2.5 in), the pipe may break under certain conditions.

1 to 100 days. The daily trend is updated every five minutes. • Moisture sources: − Relative humidity (%RH) level: This value is measured by the Hydran M2-X moisture sensor. − Relative humidity (%RH) hourly average: This value is calculated based on the relative humidity calculations made during a period of time ranging from 1 to 170 hours.
Page 112: Setting The High Alarm Condition
Before setting the gas or moisture level High alarm condition, the gas and moisture level readings should be monitored over a minimum period of two weeks. A simple method to monitor this value is to consult the Hydran M2-X’s history files using its keypad (see Section 4.4.2).
