SERIES 525 RAINFALL SENSORS DESCRIPTION The sensor consists of a gold anodized aluminum collector funnel with a knife-edge that diverts the water to a tipping bucket mechanism. The models TR-525I and TR-525USW are calibrated in inches (.01” per tip) and model TR-525M is calibrated in millimeters (.1mm per tip). A magnet is attached to the tipping bucket, which, as the bucket tips, actuates a magnetic switch. Thus, a momentary switch closure takes place with each tip of the bucket.
ORDERING INFORMATION Model # Description TR-525I Rain Gauge, 6.06” collector, English (Please specify for calibration of 0.2 mm/tip) TR-525USW Rain Gauge, 8.
MODEL 525 TIPPING BUCKET RAIN GAUGE TRANSMITTER INSTALLATION INSTRUCTIONS A clear and unobstructed mounting location is necessary to obtain accurate rainfall readings. This transmitter has provisions for mounting two ways, surface mounting and mast mounting. Surface mounting is recommended where possible. The transmitter housing MUST be mounted in a LEVEL position and in a location free from vibration.
FIELD CALIBRATION TR-525I & TR-525M Absolutely accurate calibration can be obtained only with laboratory equipment, but an approximate field check can be easily made. The tipping bucket mechanism is a simple and highly reliable device. The transmitter must be located in a clear area, away from trees, buildings, etc. It must also be mounted level. Accurate readings will not be obtained unless the transmitter is mounted in a level position. The mechanism must be clean.
MODEL TTH-1315 TEMPERATURE HUMIDITY SENSOR DESCRIPTION The Texas Electronics, Inc.

PROPER EXPOSURE OF METEOROLOGICAL INSTRUMENTS Generally recognized guidelines follow which depict "ideal" sensor mounting locations. These guidelines or "rules of thumb" are only suggestive in nature in an attempt to aid the user to selecting optimum representative sampling locations for a particular sensor. Reference was made to US Weather Bureau Installation criteria in preparing this data (See Reference 1).
PRECIPITATION GAUGES: Rain gauges should be installed on a level plot of ground, at a distance from any object of at least two and preferably four times the height of the object above the top of the gauge. All types of gauges must be exposed with the rim of the receiver in a horizontal plane and at a level well above the average level of snow surfaces. Roof-mounting of rain gauges should be avoided when possible.
Step 2: Attach wind vane and counter-weight to the direction sensor head. Loosen the two set screws on the top of the wind vane (upper unit). Insert the vane and counter-weight into the holes. Be sure to press both parts all the way in and make sure the flat areas on each arm face the set-screws. Tighten the set screws. Note: For optimum performance and maximum bearing longevity you may wish to fine-tune the balance of both wind sensors.
Two methods of aligning the vane are available. The first method involves loosening the large set screw at the bottom of the wind direction sensor so that it will rotate on the U-arm. Turn the bottom half of the sensor until the compass readings and the indication match then retighten the set screw.
Warranty Texas Electronics, Inc. (hereafter TEI) warrants the equipment manufactured by it to be free from defects in material and workmanship. Upon return, transportation charges prepaid to TEI, within three (3) years of original shipment of sensors and one (1) year of original shipment of electronics, recorders and indicators, TEI will repair or replace, at its option, any equipment which it determines to contain defective material or workmanship, and will return said equipment to purchaser, F.O.B., TEI.
