Product Description
TS PRS-01 piezoelectric rain gauge is a small measuring instrument developed and produced by our company to monitor rainfall. The working principle of the piezoelectric rain gauge is to use the piezoelectric effect of the piezoelectric vibrator to convert the mechanical displacement (vibration) into an electrical signal, and then according to the voltage waveform change of the impact energy of the raindrop, the size of the rainfall can be obtained. In this way, the weight of a single raindrop can be measured and the rainfall can be calculated. This product has the advantages of fast response, large measurement range, high measurement accuracy, and maintenance-free; it is widely used in many fields such as geological disasters, sponge cities, smart transportation, smart agriculture, urban drainage systems, etc.
| Product features | Real-time output of rainfall cumulative value, rainfall intensity (1 minute average), predicted rainfall (calculated based on the rainfall in the past 5 minutes, the rainfall in the next 1 hour and 24 hours), and alarm (according to the rainfall in the past 1 hour to reach the rainstorm level) ). It can be equipped with GPRS wireless transmission, solar power supply, GPS positioning and other functions, and can increase the monitoring of meteorological elements such as hail, temperature and humidity, air pressure, wind speed and direction. |

1. Fully electronic kinetic energy type, rainfall monitoring identifies rainfall according to the intensity of raindrops. 2. Measure instantaneous rainfall output, real-time measurement data can be output from drizzle to extremely heavy rain. | 1. The measuring range is 0~24mm/min, It is 6 times the measuring range of the traditional tipping bucket rain gauge. 2. It can be accurately measured in the case of instantaneous heavy rain and extreme heavy rain, without limit of extreme value | 1. Integrated design, all components are integrated inside the product, no exposed parts and connecting wires, easy installation and maintenance, extremely low failure rate, and long service life. | 1. Integrated structure, small size and light weight. The hoop-type installation is simple and convenient. A single site can complete the operation in 10 minutes. 2. Simple structure, light weight, quick dismantling and no engineering pollutants. | 1. No need for manual maintenance, remote calibration and upgrade, etc., maintenance-free. |
 |
1. The rain gauge collects rainwater, and determines the rainfall value by counting the number of dumping buckets by volume. 2. There is usually a delay in rainfall data, especially during light rain, heavy rain, and heavy rain, which results in a deviation from the real-time situation. | 1. The measuring range is 0~4mm/min. 2. In the case of instantaneous heavy rain, heavy rain, and extremely heavy rain, there will be a delay in the data, and it will not be able to measure when it exceeds the extreme value of the device. | 1. Combined design, RTU, DTU, power supply unit and other components are independent of each other and need to be installed separately, with more exposed connections, higher failure rate and shorter service life. | 1. A cement base weighing 0.5 tons needs to be prepared one week in advance, and the rain gauge, power supply system, RTU, base bracket, etc. shall be installed separately on site. It is time-consuming and labor-intensive. 2. It cannot be moved after installation, and it is difficult to clean up after disposal. | 1. The rain gauge is often blocked, requiring regular manual maintenance and calibration every month. Maintenance costs are several times or even ten times higher than equipment costs, and there are hidden dangers to personnel safety in special installation locations. |
