How to install solar water heater temperature and water level sensor?

Simply insert the sensor from the exhaust port on the top or the overflow port on the side.

Solar water heater is a device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of water floatinghot. and cold water flows to cause microcirculation in the water.

Solar water heaters that need to install their own temperature and water level sensors generally do not fill water automatically. The upper water storage tank is connected to the atmosphere. There is an air outlet at the highest point (covered by a plastic cover), and there is an overflow port on the side. The water pipe inside to see if the water is full is connected to the overflow port.

Additional temperature and water level sensors are essentially electrically contacted water level gauges with several electrodes (some attached to a pipe) distributed at different heights inside the tank of water as long as the water reaches the electrodes and the water. level gauges will indicate where the water is.

The temperature and water level sensor can be installed from the top, side et the bottom. However, bottom loading requires a special opening in the water tank, so apart from replacing the original one, it is usually not necessary to install a temperature and water level sensor. Most top- and side-mounted temperature and water level sensors are universal. The easiest way is to remove the original water pipe from the overflow port on the side of the water tank (the innermost horizontal pipe can be retained). Insert the temperature and water level sensor into it, leaving only a small bit of pole in the back; If you install it from the exhaust port above, pay attention to the insertion depth so that the height of the upper electrode is slightly lower than that of the upper electrode. the overflow port.

The analysis is as follows:

1. There is a rubber stopper which is similar to the stopper of ae thermos bottle. Hold the rubber stopper and. shake it back and forth, then remove it. When choosing, pay attention to whether there are two or four wires.

2. You can also purchase an instrument set including solenoid valve and sensor online without disassembling the original sensor, which costs only 100 yuan. The sensor can be inserted into the exhaust hole on the water. tank, and it is very convenient to use.

Like air speed, water speed can also be measured through an orifice plate. However, the main purpose of measuring water flow is to determine heat. There are many types of heat meters on the market capable of measuring flow rates, and the principles vary.

As shown in the figure:
