The main control parameters for the selection of mechanical heat meters are: nominal diameter, common flow, large flow, small flow, rated pressure , large pressure loss, temperature range, temperature difference range, etc. The initial investment for a mechanical heat meter is relatively low. The mechanical flow sensor measures the flow rate of the thermal medium by measuring the rotation speed of the impeller. According to the size classification, it can be divided into two categories: small diameter (≤) and large diameter (≥). According to the internal structure classification, small-diameter flow sensors are divided into single-stream type and multi-stream type. Among them, the single-stream type has a shorter impeller life due to uneven impact of water flow. Large diameters are divided into two types: horizontal screw-wing type and vertical screw-wing type. The former can be installed horizontally or vertically, while the latter can only be installed horizontally. In order to prevent the rotating parts of the flow sensor from being blocked, the flow sensor of the heat meter has certain requirements for water quality. The small flow rate of the heat meter should be smaller than the small flow rate of the measured load. The large flow rate of the heat meter should be greater than the large flow rate of the measured load. The common flow rate of the heat meter should be close to the measured rated flow rate. The rated pressure of the heat meter should be consistent with the measured system pressure. consistent. According to the application function requirements of the heat meter (such as household meters, building meters, heat source meters, etc.), select heat meters with corresponding accuracy levels and quality. A water meter refers to an instrument that measures water flow. Mostly cumulative flow measurements of water. Generally divided into two categories: volumetric water meters and velocity water meters. The accuracy of the former is higher than that of the latter, but it has high requirements on water quality, and it is easy to be blocked when the water contains impurities. A meter that records tap water consumption. It is installed on the water pipe. When the user releases water, the pointer or wheel on the meter rotates to indicate the amount of water passing through.
