1. Detailed explanation of installation steps for steam flowmeter probes
The core of steam flowmeter probe installation lies in accurate positioning, standardized hole welding, accurate insertion of probes, and rigorous sealing testing to ensure measurement accuracy and system safety. 1. Preparation before installation • Confirm installation location: Select a straight section of the steam pipeline, with the upstream straight section length not less than 10 times the pipe diameter and the downstream straight section length not less than 5 times the pipe diameter, avoiding interference sources such as valves and elbows. • Cleaning the pipeline: Thoroughly remove debris and rust from the pipeline to prevent interference with the probes operation or damage to the pipeline. • Check the probe: Carefully inspect the appearance of the probe for any damage and check if the accessories are complete.
2. Installation process • Drilling: Use a drilling tool to select and locate a hole in the pipeline, and the hole diameter should be accurately matched with the installation size of the probe. Welding base: Weld the matching base to the opening to ensure a secure and well sealed welding. Pay attention to controlling the welding temperature to prevent deformation of the pipeline. • Install ball valve (optional): If online maintenance is required, the ball valve can be installed on the base first for uninterrupted operation. Insert probe: Close the ball valve (if installed), insert the probe into the base so that its sensing part is at the center of the pipeline, and the insertion depth should meet the requirements. • Fixed probe: Use sealing gaskets and nuts to firmly fix the probe to ensure sealing effect

2. Several factors affecting the accuracy of steam flow measurement
Several factors affecting the accuracy of steam flow measurement: Commonly used steam flow meters are divided into two types: first, vortex flow meters (usually referred to as steam flow meters). Vibration on site can affect the accuracy of the flow meter, and the quality of the temperature sensor or damage can affect the accuracy of the flow meter.
. The quality or damage of pressure sensors can affect the accuracy of flow meters. The installation method and quality of the flowmeter probe are also important factors affecting the accuracy of the flowmeter. On site installation method: a. The straight pipe section requires ten in the front and five in the back, b、 Keep the front and rear ends unobstructed and leak free, etc. 2: Orifice flowmeter 1. The range ratio for vortex flowmeter to achieve outstanding measurement effect is 1:10, that is, the minimum flow rate: the maximum flow rate. The range ratio for orifice flowmeter to achieve outstanding measurement effect is 1:5, that is, the range ratio affects accuracy. 2. The quality of temperature sensor or damage will affect the accuracy of flowmeter. 3. The quality
