What should be noted when installing a steam flowmeter??
When installing a steam flowmeter, the following issues should be noted: piping requirements: The inner diameter of the upstream and downstream piping at the installation point of the steam flowmeter should be the same as the inner diameter of the flowmeter to ensure smooth fluid flow and accurate measurement of the coarse wax strip.. Requirement for straight pipe section: The flowmeter must be installed horizontally on the pipeline, and the pipeline inclination should not exceed 5 °. The axis of the flowmeter should be concentric with the axis of the pipeline and flow in the same direction. The upstream pipeline length of the flowmeter should have an equal diameter straight pipe section of not less than 10D. It is recommended that the upstream straight pipe section be 20D and the downstream be 5D to improve measurement accuracy. Requirements for bypass pipe: Cut off valves should be installed on the front and rear pipelines of the flowmeter, and bypass pipes should be set up so as not to affect the normal use of the rock reed medium during flowmeter maintenance. The flow control valve should be installed downstream of the flowmeter, and the upstream shut-off valve must be fully opened during use to avoid unstable flow. Installation site cracking: Steam flow meters should be installed in a location that is easy to maintain and free from strong electromagnetic interference and thermal radiation to ensure their normal operation and extend their service life. External environmental requirements: It is best to install steam flow meters indoors. If it must be installed outdoors, sun protection, rain protection, and lightning protection measures should b
2. Requirements for the installation of steam pipe flow meters
The core requirements for the installation of steam pipe flow meters can be summarized into nine aspects: grounding protection, position selection, direction angle, etc. Strictly following these requirements can ensure the accuracy of measurement and equipment stability.
. 1. Installation and Grounding - Strictly follow the instructions for installation, and measure the grounding resistance value to be ≤ 10 Ω after completion. -Equipotential bonding wires should use multi strand copper bundle wires with an area of ≥ 16mm ², and instrument grounding wires should use wires of the same material with an area of ≥ 6mm ². 2. Installation location selection - avoid strong vibration, high temperature/radiation heat sources, and corrosive environments. If unavoidable, shock-absorbing short joints or protective covers should be installed. -Outdoor installation should be equipped with sunshade and rainproof measures, and kept away from strong magnetic field equipment such as ferromagnetic objects, large motors, transformers, e
