TE525 Tipping Bucket Rain Gage

1. Introduction

The TE525 is an adaptation of the standard National Weather Service tipping bucket rain gage. Output is a switch closure for each bucket tip. Three models are available:

• TE525 6 in. orifice 0.01 in. tip

• TE525WS 8 in. orifice 0.01 in. tip

• TE525MM 24.5 cm orifice 0.1 mm tip

Before installing the TE525, please study:

• Section 2, Cautionary Statements

• Section 3, Initial Inspection

• Section 4, Quickstart

2. Cautionary Statements

• The TE525-series tipping bucket rain gages are precision instruments.

Please handle them with care.

• Care should be taken when opening the package not to damage or cut the

cable jacket.

• Sensor is factory calibrated and should not require field calibration. Refer

to Section 9, Maintenance, for field calibration check and factory calibration.

• Debris filters, funnel, and bucket reservoirs should be kept clean.

• The black outer jacket of the cable is Santoprene

was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.

3. Initial Inspection

• Upon receipt of the tipping bucket, inspect the packaging and contents for

damage. File damage claims with the shipping company.

rubber. This compound

• Immediately check package contents against the shipping documentation

(see Section 3.1, Ships With). Contact Campbell Scientific about any discrepancies.

• The model number and cable length are printed on a label at the

connection end of the cable. Check this information against the shipping documents to ensure the expected product and cable length are received.

TE525 Tipping Bucket Rain Gage

3.1 Ships With

The TE525 ships with:

(1) Calibration sheet (2) Hose clamps from original manufacturer (1) ResourceDVD (3) Screws from original manufacturer

4. Quickstart

Please review Section 7, Operation, for wiring, CRBasic programming, and Edlog programming.

4.1 Siting

The rain gage should be mounted in a relatively level spot which is representative of the surrounding area. The lip of the funnel should be horizontal and at least 30 cm above the ground. It should be high enough to be above the average snow depth. The ground surface around the rain gage should be natural vegetation or gravel. It should not be paved.

4.2 Mounting

NOTE

The rain gage should be placed away from objects that obstruct the wind. The distance should be 2 to 4 times the height of the obstruction.

• The pipe used to mount the bucket must be vertical. Use a torpedo level or

something similar to get it as vertical as possible.

Take the funnel off of the top of the bucket and look inside towards the

•

bottom of the bucket — notice the bubble level. Center the bubble level while mounting the bucket to the pipe. Replace the funnel and seat it completely when the installation is complete.

The CM300-series mounting poles provide a stainless steel 1.5 IPS vertical pole for mounting the TE525 rain gage. Pole length is 58 cm (23 in), 119 cm (47 in), and 142 cm (53 in) for the CM300, CM305, and CM310 models respectively. The CM300-series offers pedestal base options as well, as shown in FIGURE 4-2.

Use the enclosed hose clamps to mount the gage as shown in FIGURE 4-1. The lip of the gage should be at least 5 cm (2 in) above the post or pole. Level the rain gage after mounting it.

Before final leveling, press either end of the bucket down against its stop to make sure the bucket is NOT hung up in the center.
