How does a tipping bucket stainless steel rain gauge work?

The tipping bucket rain gauge working principle is counting the number of times the tipping bucket falls. The tipping bucket is made of stainless steel and divided into two half-cone chambers with equal volume by a partition in the middle. It is a mechanical bistable structure. When one chamber receives water, the other chamber is waiting. When it rains, the rainwater collected by the water receiving port enters the metering bucket through the funnel. When the volume of the received rainwater reaches the predetermined value of 0.2mm, the chamber will overturn due to gravity and be waiting, and the other chamber will be in a state of receiving water. When the water receiving volume reaches the predetermined value, the bucket will overturn again and be waiting. Magnetic steel is installed on the sidewall of the tipping bucket, which scans from the side of the dry reed tube when the tipping bucket flips to make the dry reed tube on and off. That is, every time the tipping bucket is overturned, the dry reed tube will be switched on and send out a pulse or 485 signal. This is the working principle of the stainless steel tipping bucket rain gauge.

FAQ

What are the rain gauge accessories?

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.

• 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.
• 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.
