Capacitancefuel level sensors operate on the basic principle of the linear variation of the electrical capacity formed between the inner and outer shell with the content shifty, transformed variation of the content level to 4~20mA, 0~5V, RS232, RS485 etc., could display liquid level height directly or be sent to the remote monitoring and control system by satellite.
Note：C0 is constant capacitance
εr: Liquid dielectric constant
ε0: Air dielectric constant
hx: Liquid level
CC=C0+△C= C0+ K(εr－ε0) *hx / ln (r2/r1)
- Approvals: Exia IIBT6
- Easy to operate
- Measurement range:self -calibration(by user)
- Rod length adjustable (by user)
- High precise liquid level measurement of gas tank, oil tank truck, logistics vehicles, construction vehicles, oil depot, water, milk etc.
- Oil tank level detection of Steel,oil field,chemical industry,cement,thermal power plant,light industry and sewage disposal etc.
