What is the lifespan of an electromagnetic flowmeter. DN200 water measurement. Accurate at room temperature and pressure!! Tell me at least ..
Whether to install indoors or outdoors... What is the indoor temperature... How is your work environment, Wang Hui? Yin Nian... These are necessary to determine the lifespan of the electromagnetic flowmeter. Generally, electromagnetics can be used for 2-5 years (in standard environments). If the medium contains sulfuric acid, what electrode do you choose? Do you use tetrachloroethylene or what?
2. How to set the quota for DN200 electromagnetic flowmeter? Thank you. The DN200 electromagnetic flowmeter is calculated based on the valve installation quota of the corresponding pipe diameter multiplied by 0.7. In the book "C-10 Automation Control", it is stated that the instrument flow meter installed directly on the pipeline executes the valve installation, and the corresponding project personnel and machine are multiplied by a coefficient of 0.7. The installation of the electromagnetic flow Zen hidden meter in the He Hall is basically the same as the installation of the instrument flow meter. 3.

4. How to select Emerson flow meters based on pipe diameter?
Emerson flow meters are mainly selected based on the type of flow meter and the actual flow range. The core is to match the pipe diameter with the flow range to avoid measurement accuracy decline or equipment damage caused by improper pipe diameter.
. 1. The range of pipe diameters and the type of flow meter are compatible with Emersons mainstream flow meters. The range of pipe diameters is different. The Coriolis flow meter is suitable for small pipe diameters, usually DN6-DN200 (1/4 inch -8 inches). Based on the principle of Coriolis force, it has high measurement accuracy for fluid density and mass flow, and is commonly used
