Level gauge
Thread Content
The resin tank under vacuum comes with a heated outer coil for stirring; how should the level gauge be selected?
A magnetic float level gauge installed on the tank wall would be better, right?
Magnetic flap? Radar? Infrared? Many kinds
The resin material has high viscosity and contains volatiles, which can easily clog the probe and float ball
SMD? Coil on the outside of the tank
Radio frequency admittance can be considered; we use it in high-viscosity and high-temperature conditions, and although it isn’t particularly accurate, it’s still acceptable.
For top-mounted installation, radar level gauges and radio frequency admittance sensors should work, but the transmission angle needs to be taken into consideration; for side-mounted installation, double-flange diaphragm types can be used.
There aren’t many options; radar, I guess.
