Photovoltaic weather meter

1.Introduction to photovoltaic meteorological instrument products

Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of micro meteorological instruments, has been committed to the promotion and application of micro meteorological instruments and meteorological environment solutions. With a complete production chain, a strong technical team and a comprehensive marketing team, the meteorological products we develop and produce such as ultrasonic wind speed and direction meters, five-element micrometeorometers, six-element micrometeorometers and small automatic weather stations have been widely used in In the fields of photovoltaic power generation, meteorological monitoring, urban environment monitoring, wind power generation, navigation ships, aviation airports, bridges and tunnels, etc., we have customers all over the country and have achieved good social and economic benefits.

Compared with traditional miniature weather instruments, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The FT-WQX8B eight-element micrometeorometer innovatively combines wind speed, wind direction, temperature, humidity, air pressure, total thermoelectric radiation, total radiation daily cumulative radiation, and component temperature (backplane temperature) through a highly integrated structure. It can realize 24-hour continuous online monitoring of outdoor meteorological parameters, and output eight parameters to the user at one time through the digital communication interface.

2. Product Features of Photovoltaic Meteorometer

1. The ultrasonic probe is hidden in the top cover to avoid interference from rain and snow accumulation and avoid obstruction by natural wind (utility model patent, patent number ZL 2020 2 3215713.X) ☆

2. The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5) ☆

3. The total thermoelectric radiation is integrated on the top of the miniature weather instrument, and the angle is adjustable from 0-50°.

4. The backplane temperature is connected in parallel with the micro weather meter through a 6-hole expansion box to facilitate on-site installation and debugging by customers.

5. Adopt advanced sensing technology, real-time measurement, no starting wind speed☆

6. Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system

7. High integration, no moving parts, zero wear and tear

8. Maintenance-free, no on-site calibration required

9. ASA engineering plastics are used for outdoor applications without discoloration all year round.

10. The standard output signal of product design is RS485 communication interface (MODBUS protocol); optional 232, USB, and Ethernet interfaces support real-time reading of data☆

11. Optional wireless transmission module, minimum transmission interval is 1 minute

12. The probe is a snap-on design, which solves the problem of looseness and inaccurateness during transportation and installation☆
