What type of level gauge should be installed in ethanol solution storage tanks? Please provide recommendations
Thread Content
95% ethanol solution storage tank, 10 m3; two openings are provided at the top, one of which is used as a vent valve
Ultrasonic waves, radar, radio frequency admittance, and magnetostrictive sensors can be used for the tank top; it’s not clear whether it’s a vertical tank or a horizontal tank
Ultrasonic waves don’t work; the medium will evaporate. If the dielectric constant meets the requirements, consider radar. If there is an opening on the side of the bottom of the storage tank, a single-flange level gauge would be the most ideal choice; simultaneously, the negative pressure side of the single flange should be connected to the top of the storage tank in order to achieve gas-phase equilibrium.
The GDLD601 guided-wave radar level gauge can work with a cable; alcohol causes evaporation, which makes ultrasonic sensors less effective. In terms of cost-performance and performance, guided-wave radars are far more reliable
Radar, cable-type. Rosemont’s, seems to be around 2W
Rosemount gauge radar; the estimate is around 100,000
Things like this are usually expensive, right? The quality requirements are quite strict
If the storage tank does not have openings, an external-mounted level gauge such as the ZHH-LM-CTA10 can be used; it has an accuracy of 0.1%, operates on a four-wire system, is powered by 24VDC, is explosion-proof according to ExdIICT6 standards, has an IP67 protection rating, provides a 4-20mA output, features an NPT1/2 electrical interface, and includes an on-site display. If the storage tank has openings, measurement methods such as ultrasound, radar, radio frequency admittance, and magnetostrictive sensing can be used.
Radio frequency admittance and magnetostriction; the price isn’t particularly high, and the performance is quite good
Any level gauge manufactured by a manufacturer that has an explosion-proof certification available for verification can be used
