Seek flow meter selection guidance
Thread Content
Medium: CaCl2 saline solution; Temperature: -20 degrees; Pressure: 0.1 MPa; Flow rate: 10–20 m3/h. Requirements: Simple design and easy maintenance. It’s not necessary to have remote transmission – only on-site display is sufficient. I would appreciate it if experts could help determine which type of flow meter is suitable for this medium. Thank you. I have initially considered water meters and metal rotor flow meters – I’m not sure if these are appropriate options
For applications with low flow rates and without the need for remote transmission, a rotameter can be considered.
Use an electromagnetic flowmeter, wow; the following is just to fill up the words
I’m not sure if the poster has considered the corrosion issue caused by chloride ions; if so, rotors and turbines are options to consider.
If only an instantaneous flow rate is required and vertical installation is possible, a glass rotor flow meter or a metal rotor flow meter can be chosen. If it is necessary to display instantaneous and cumulative flow rates, it is recommended to use an electromagnetic flowmeter (for horizontal or vertical pipelines) ； Metallic rotameter (vertical pipe) ； Turbine flowmeter (horizontal pipeline). It is not recommended to use water meters. The most cost-effective option is the electromagnetic flowmeter.
If precision requirements are not high, my opinion is: ultrasound~~
Metal tube rotameters can be used, but the glass tube rotameters mentioned on the 7th floor cannot be used – low temperatures of -20 degrees will damage the glass tubes.
