Detailed Description

The CM240 may be attached to a CM300-series mounting pole, or to a user-supplied 1.5 IPS (1.9" OD, unthreaded) pipe. The pipe should be long enough to place the gage's orifice at a one-meter height. The pole or pipe can be placed directly into a concrete foundation, attached to a concrete foundation using j-bolts, or self-supported with legs. A concrete pad is recommended.

The rain bucket mounting hole bolt pattern is adjustable to these three diameters:

  • 23.24 cm (9.15 in.)
  • 24.44 cm (9.62 in.)
  • 25.6 cm (10.08 in.)
