1. Hello, what is the principle of the underfloor heating flowmeter?
The principle of the underfloor heating flowmeter is to detect the temperature difference and flow rate of the supply and return water.. Detailed explanation of underfloor heating flow meter reading: Calculate the resistance of each underfloor heating pipe, the formula is: total length of underfloor heating pipe * underfloor heating pipe area=total water storage capacity. Calculate the resistance of each path of the underfloor heating pipe. Then there are several paths, and adding them together gives the total resistance. The head of the shielded pump for water supply, that is, how high the pressure is. Divide the pressure of the shielded pump by the total resistance. The obtained value is the length of water flow in the underfloor heating pipe per second (in meters per second). The first major reason for the lack of geothermal heat is the uncleaned underfloor heating pipes, which are caused by the accumulation of scale. After long-term use of underfloor heating equipment, the combination of calcium and magnesium ions in the underfloor heating pipes can form scale, impurities, etc. The thermal conductivity of scale is extremely poor. During the heat exchange process, if the scale increases from 0mm to 0.3mm, the heat exchange rate will decrease to 79%. Additional information: The introduction of underfloor heating flow is as follows: When the thickness of scale reaches 0.3mm, 21% of the heat cannot be converted properly, resulting in geothermal heat not being generated. So it is recommended that users clean the underfloor heating pipes in a timely manner, and it is best to have a professional cleaning of the underfloor heating pipes ever

2. How much underfloor heating flow is considered normal?
The normal range of underfloor heating flow is clear. Answer: The normal range of underfloor heating flow may vary depending on the specific usage environment and conditions. Generally speaking, the normal flow rate of underfloor heating should be around 2 to 3 times the cross-sectional area of the circulating pipeline per hour. For example, if the cross-sectional area of the pipeline is DN20, its flow rate is approximately DN × DN × π ÷ flow rate ≈ hourly water volume. Under normal heating conditions, in order to ensure uniform temperature distribution and provide comfortable heating effect, the recommended flow rate range in the underfloor heating system should be maintained. The specific flow rate values may vary due to factors such as pipeline model and design temperature. The detailed explanation is as follows: the standard for underfloor heating flow is determined by factors such a
