1. Urgent request for online English translation, do not use translation tools, it is best to have manual translation, grammar and sentence fluency 4 Requirements 4.1 Design Requirements When designing the heating system, the heat meter supplier"s installation instructions shall be followed. When designing a heating system, the supplier of the temperature sensor provides the following installation instructions. NOTE For DN 25 and smaller, it is possible to use short probes. To achieve good temperature sensitivity, probes should be installed without temperature pockets. Temperature pockets should only be used when required for safety reasons. Note that for diameters of 25 and smaller, use short probes. To achieve the best temperature sensitivity, the probe should remove the temperature package during installation. The temperature pack is only used when safe conditions are met.

4.2 Installation requirements The heat meter shall be installed in accordance with the supplier"s instructions. Refer to the instructions provided by the supplier for installing the temperature sensor. Before installation, the circuit into which the flow sensor is to be installed shall be thoroughly flushed to remove debris. The strainer, where fitted, shall be cleaned. Before starting the installation, make sure that the circuit of the flow sensor has been installed and thoroughly remove any installation debris. Secure the filter and ensure it has been cleaned. The heat meter shall be protected from the risk of damage by shock and vibration induced by the surroundings at the place of installation.The heat meter shall not be subjected to undue stresses caused by pipes and fittings. The temperature sensor should avoid vibration caused by th

e installation site environment and damage caused by vibration. Temperature sensors should avoid excessive pressure caused by pipelines and devices. The pipe lines of the heating system up and downstream of the heat meter shall be adequately anchored. The heating system pipeline installed on the upper and lower parts of the temperature sensor should be firmly fixed. Heat meters designed to operate from an AC mains supply shall be wired in accordance with wiring regulations applicable. The temperature sensor is supplied by AC power supply and equipped with wires that comply with wire regulations. The AC-mains power supply shall be secured against accidental interruption. However, circuit protection shall be incorporated according to the state of the art, to safely disconnect the device when electrical problems occur.AC Once the power supply is interrupted by an emergency, ensure that the power supply is protected. When a circuit failure occurs, it is necessary to provide circuit protection that is consistent with the level of technological development when safely disassembling the settings. Measurement signal leads shall not be laid directly along side other leads such as mains supply cables, low voltage supply cables and data communication cables and shall be independently supported. The separationbetween those groups shall not be less than 50 mm. Signal measurement lines should not be installed directly with other lines (such as main power lines, low-voltage lines, data transmission lines), as they are installed independently. The installation interval distance of these wires shall not be less than 50 millimeters. Mains and external signal cables longer than 10 m shall in areas where lightning is frequent be protected w
