1. Is the flow meter in front of the five finger arrow or behind the arrow?
The first five and the last three refer to the straight pipe section distance of 3 or 5 times the diameter (unit) in front or behind the rock search surface where the pipeline is opened. For example, if the flow meter is DN100, there should be a 5 * 100mm straight pipe section at the front and a 3 * 100mm straight pipe section at the back to ensure proper distance. Refer to Wang Shens figure below for calculation method:

Installation requirements for flow meters - Key guidelines for ensuring accurate flow measurement in industrial production, energy transportation, and other fields. The installation of flow meters is crucial to ensure the accuracy of flow data. The following is a comprehensive analysis of the installation requirements for flow meters, aimed at helping users correctly install flow meters to ensure accurate flow measurement.
1. Fine selection of installation position for straight pipe section requirements: Sufficient straight pipe sections should be ensured before and after the flowmeter. It is generally recommended that the length of the upstream straight pipe section be no less than 10D (D is the inner diameter of the pipeline), and the downstream straight pipe section be no less than 5D. This is to ensure that the fluid can recover a stable flow state after passing through fittings, valves, and other components, and to ensure that the flowmeter captures a uniform and consistent flow velocity signal.

2. Installation direction and flow direction adaptation of differential pressure flowmeter: The throttling device should be installed perpendicular to the pipeline axis, and the connection of the pressure pipe should ensure no leakage or blockage. The positive pressure side corresponds to the high pressure end, and the negative pressure side is connected to the low pressure end.
. Turbine flowmeter: The fluid flow direction should be consistent with the rotation direction of the turbine blades, otherwise the turbine cannot rotate normally and may even be damaged. Quality flowmeter: During installation, it is necessary to ensure that the sensor is in a horizontal state to ensure that the Coriolis force can act in the optimal vertical plane of gravity and avoid measurement errors caused by excessive tilt angles.Thirdly, the sealing and concentricity of pipeline connections should be the top priority: the sealing of the connection between the flowmeter and the pipeline should be ensured to prevent fluid leakage.
. Use suitable sealing gasket materials, such as chemical resistant polytetrafluoroethylene gaskets, graphite gaskets, etc., and tighten the connecting bolts fol
