Which is better, an electric float level gauge or a double-flange level gauge?
Thread Content
For liquids with high viscosity, at a temperature of 400 degrees, which one is more effective? Please share your opinions
In my opinion, double-flange level gauges are the better choice; it’s ideal to fill the pressure guide tube with an isolating fluid
Double-flange level gauges are better; for electric float level gauges, an internal float is required
It can be used, but it doesn’t work well; it’s recommended to try using an internal float ball.
I think a float level gauge is still the better choice; double-flange level gauges cannot withstand such high temperatures.
The diaphragm of high-temperature medium double-flange transmitters cannot withstand it; the internal float can be tried as an alternative, but maintenance is possible only after the system is stopped and cooled down.
Neither the electric float level gauge nor the double-flange level gauge is very suitable; it is recommended to use an internal float instead.
The electric float contains a weighing cylinder; for media with high viscosity, the reaction is slow, so it is not very suitable； Double flanges can be used in that case, but they don’t perform very well in our company’s operations; especially in winter, they tend to solidify, which makes maintenance quite troublesome.
Electric float level gauges require a steam jacket; dual-flange transmitters have too high temperatures and need cooling devices, so they are not very effective. If the measurement range is not very large, an internal float level transmitter can be used – it can handle viscosities up to 400 degrees!
It can’t be generalized; it depends on the situation, as each has its own advantages and disadvantages
