1. Introduction
The TE525-series tipping bucket rain gages are adaptations of the standard National Weather
Service tipping bucket rain gages. They funnel rain into a mechanism that tips when filled to the
calibrated level. The TE525 and TE525WS measure in 0.01-inch increments and the TE525MM
measures in 0.1-mm increments. The TE525WS conforms to the National Weather Service
recommendation for an 8-inch funnel orifice. The TE525 and TE525MM have an orifice diameter
of 6 inch and 24.5 cm, respectively.

2. Precautions
l
READ AND UNDERSTAND the
section at the back of this manual.
l
TE525-series tipping bucket rain gages are precision instruments that must be handled
with care.
l
Sensor is factory-calibrated and should not require field calibration. Refer to
(p. 13) for field calibration check and factory calibration.
l
During field installation, ensure that you have removed the small rubber band that secures
the tipping mechanism during shipping.
l
Debris filters, funnel, and bucket reservoirs should be kept clean.
l
Santoprene® rubber, which composes the black outer jacket of the TE525 cable, will
support combustion in air. It is used because of its resistance to temperature extremes,
moisture, and UV degradation. It is rated as slow burning when tested according to U.L. 94
H.B. and passes FMVSS302. However, local fire codes may preclude its use inside buildings.
