    About - Optical Rain Gauge

    Our optical rain gauge has RS485 signal output and pulse-type signal output. Among them, the RS485 output optical rain sensor can be combined with a small anémomètre à ultrasons to form an ultrasonic weather station.

    Principe de fonctionnement

    When raindrops pass through the sampling space, the raindrops will block the laser, and the light signal received by the receiving sensor and the electrical signal (such as voltage or current) converted from the light signal will change. When the raindrop passes through the sampling space, it will receive the electrical signal from the sensor. Restore the previous state. When the raindrops traverse the sampling space, the electrical signals of the receiving sensor are processed, and the time for the raindrops to traverse the sampling space can be obtained.

    • Rain sensor diameter: 6cm
    • Power supply: 9~30V DC
    • Power consumption: <0.24W (12V DC, current less than 20mA)
    • Resolution: Standard 0.1mm
    • Typical accuracy: ±5% (based on data from Renke laboratories)
    • Max. instantaneous rainfall: 24mm/min
    • Working environment: -40°C~80°C, 0~95%RH with non-condensing
    • Operating pressure: Standard atmospheric pressure ±10%
    • Signal output: RS485/Pulse

    Avantages

    Avantages

    Compared with the tipping bucket rain gauge: the optical rain gauge is small in size, simple to install, and easy to maintain. The optical rain gauge uses electronic optics and a series of microelectronic filtering, amplification, and detection technologies. This principle has the advantage of sensitivity. During installation, because the optical rain gauge is non-mechanical and non-contact measurement, there is no horizontal installation requirement, so the installation is simple and the subsequent maintenance is also convenient. The shell has smooth lines and an easy-to-maintain design, which is not easily blocked by fallen leaves.

    Maintenance

    Before installing the optical rain gange, it must be ensured that the surface of the cover is dry. Any water droplets will cause measurement errors. You can choose to use some desiccant in it.
    If the optical rain gauge is kept outdoors for a long time and the operating environment is harsh, the surface of the optical rain gauge should be kept clean, often wiped with a soft cloth, the rain gauge should be cleaned once a month for long-term work and must be cleaned once every three months.

    What are the rain gauge accessories?

    veswe

    all stainless steel tipping bucket rain gauge is composed of rain port, filter screen, water diversion funnel, tipping bucket bracket, tipping bucket, tipping bucket sleeve, inclination adjustment device, level adjustment device, constant magnet steel, reed pipe, a signal output terminal, drainage funnel, base, Stainless steel cylinder, base supporting feet, water diversion bucket filter screen, etc. Among them, the tipping bucket bracket is provided with a tipping bucket shaft sleeve, a round horizontal bubble, a reed tube bracket, and a signal output terminal.

    The tipping bucket sleeve of the rain gauge is an integrated rotating positioning structure.

    The tipping bucket is installed in the bearings of the two sleeves through the tipping bucket shaft, which makes the assembly and disassembly of the tipping bucket more convenient, and there is no need to adjust the distance between the two sleeves. , Brings convenience to on-site installation.

    How to maintain a stainless steel rain gauge?

    Rain gauge is outdoors for a long time and the use environment is very harsh. Therefore, the inner wall of the drain hole should be wiped with a soft cloth frequently to keep the rain hole clean. If there are foreign objects such as leaves in the drain hole, it should be cleaned in time to keep the waterway unblocked. If the rain gauge is not used for a long time, a cover should be placed on the ring mouth of the instrument to protect the rain mouth.

    How to clean the tipping bucket?

    Rain gauge is usually cleaned once a month for long-term work, and once every three months.

    The tipping bucket is a key component of the rain gauge, which directly affects the measurement accuracy of the instrument. Over time, a little dust or oil will be deposited on the inner wall of the tipping bucket. Therefore, the tipping bucket should be cleaned. When cleaning, the inner wall of the tipping bucket can be repeatedly rinsed with clean water or gently brushed.

    Why is there no data when it is raining?

    This indicates that the rainfall gauge is not outputting a signal, or there is a fault in the transmission line. Possible causes include:

    • Reed switch failure
    • Excessive distance between the magnet and the reed switch
    • Disconnected, broken, or incorrectly connected signal wires
    • Tipping bucket jammed
    • Instrument blockage
    Why is there a big difference between the rainfall number received during rainfall and the rainfall gauge?

    Possible causes include:

    1. Misalignment of the tipping bucket pivot in the rain gauge. However, such errors generally do not exceed ±10%.

    2. Improper positioning of the magnet relative to the reed switch, which can cause intermittent signals and result in occasional missed readings.

    Why can we measure rainfall even when it’s not raining?

    Check if the socket is soaked in water, which often happens after a heavy rain.
