ESMYL100 Pulse output Tipping Bucket Rain Gauge for Stainless Steel
1. product overview
Tipping bucket rain sensor is used to measure the rainfall in nature, at the same time the rainfall is converted to a digital form of digital information output, in order to meet the information transmission, processing, recording and display needs. The instrument in strict accordance with the national standard GB / T11832-2002 "tipping bucket rain gauge" design and production requirements.
The instrument is a precision double-skip bucket rain gauge, core components dump bucket using a three-dimensional streamlined design, so that the dump bucket more smooth, and easy to clean.
The instrument has been dumping the dump angle adjustment, locked in the best position on the tilt, the installation of the instrument only need to install the dump according to this manual and adjust the level of the base can be put into use, and can not adjust the dump tip angle adjustment screw.
This product is widely used in meteorological stations, hydrological stations, agriculture and forestry and other relevant departments to measure liquid precipitation, precipitation intensity, precipitation time.
Bearing port size: φ200mm; cutting edge acute angle: 40 ° ~ 45 °
Resolution: 0.2mm
Rain intensity range: 0.01mm ~ 4mm / min (allowed to pass the maximum rainfall intensity 8mm / min)
Measurement accuracy: ≤ ± 3%
Send way: pulse output
Working environment: Ambient temperature: -10 ℃ ~ 50 ℃
Relative humidity <95% (40 ℃)
Size: φ216mm × 460mm

4 installation and adjustment
1, check out the box
(1) Carefully read the product manual, check the packing list inventory equipment accessories are complete.
(2) Check whether the appearance of the instrument is damaged or not. Pay special attention to prevent the tip of the tipping bucket shaft and the water guiding tip at both ends of the tipping bucket from being touched, and do not touch the inner wall of the tipping bucket with the finger to stain the tipping bucket.
2, production and installation of cement Taiwan
Outdoor ground or roof installation, you should first make cement bench. The height of the cement platform exposed to the ground plane 22cm, size: 40cm long × 40cm wide, the plane on the plane. When installing on the ground, the height of the rain-bearing opening should be 70cm from the ground plane.
3, the installation of fixed equipment, adjust the level of bearing rain
First on the cement stage hit three diameter φ12mm deep 8 ~ 10cm mounting hole, mounting hole located on the circumference of Φ240mm 120o equal points, the expansion bolts placed in the mounting hole, the instrument base is mounted on three expansion bolts, After checking the level of the bearing rain gauge with the level ruler, lock the three legs with the lock nut, and then take off the outer tube of the instrument for spare use.
4, install the transmission signal line
Lead the signal transmission cable from the equipment room to the cement platform through the protective tube and connect it with the output terminal through the cable hole of the base.
5 install dump
(1) Remove a tip support for the tipper. Refer to Figure 1 to identify the Tip Tip Support. Lightly lift a shaft-supported handle and rotate it 90 degrees. Pull the tip support gently out of the holder mounting hole to prepare for use.
(2) Tipping the bucket with one hand so that the bucket will be placed in the center of the bracket. The two magnets on the bucket will face the reed pipe. Gently insert the tip of the bucket into the jewel bearing hole and with the other hand The removed shaft support is inserted into the bracket mounting hole until the shaft tip enters the jewel bearing hole, and then the handle of the shaft support is rotated 90 degrees downward to complete the tipping bucket. The installed dump should be able to rotate freely.
Note: Make sure the tipper shaft is always horizontal when doing this operation to avoid bending the tip!
6 install drainage funnel
Contrast Figure 2 to identify the drainage funnel, the two drainage funnel installed in the base mounting holes, and a little hard pressed down.
7 adjust the bracket level, install the outer tube
When the three dome nuts N1, N2, and N3 are kept in the unlocked state, the height of the adjusting nuts M1, M2 and M3 are respectively adjusted so that the bubbles in the horizontal bubble are centered and the dome nuts N1 and N2 are locked , N3, once again observe the level bubble in the middle. Then install the instrument stainless steel outer cylinder, and lock the outer cylinder locking screw, the instrument can be put into use.

9 the symptoms and exclusion
This table lists the general problems that may occur with the instrument, causes and troubleshooting.
|
Central station manifestations |
Rain sensor fault |
Solution |
|
Not receive the number rainfall when |
Rain sensor no signal output or transmission line failure 1, reed failure 2, magnet and reed pipe distance is too far 3, wire off or signal line off 4, skip bucket stuck 5, the instrument is blocked |
Under the station inspection 1, Reed switch 2, adjust the reed pipe distance 3, repair 4, excluded 5, clear the blockage |
|
|
1, the rain sensor dump tip tilt disorders, but this error is generally not more than ± 10% 2, magnet and reed pipe poor location, resulting in good times and bad, so that some of the signal missing 3, data collector anti-shake function failure 4, Than the rain gauge and system rainfall sensor far apart or strong wind |
1, re-titration to adjust the tilt
2, adjust the distance
3, adjust the anti-shake dynamic circuit parameters
4, objective reasons, non-instrument failure |
|
The number of rainfall, but the actual situation did not rain |
Check the socket is flooded, this phenomenon is often prone to occur after heavy rain |
Water enter treatment, re-installation |
Note: The symptoms listed in the table are not necessarily the fault of the rain gauge itself. After checking the equipment itself, you should also check whether the equipment transmission outlet, data acquisition device, telemetry terminal and other equipment is faulty and eliminate them one by one.
