Tank-installable switches for installation through a thief hatch port on a tank. In some embodiments, the switch may comprise a tubular body and a liquid level sensor. The liquid level sensor may include: a detector; a float in and moveable along a length of the lower end; and a rod connecting the float to the detector. The liquid level sensor may be configured to sense a liquid level relative to the lower end and further configured to generate a signal when at least a maximum selected liquid level is sensed.

A chemical tank level system for a wellbore chemical injection tank is provided. The system includes a pressure sensor is located downstream of the chemical injection tank where the fluidic pressure is essentially the same as the fluidic pressure at the base of the chemical tank. The pressure sensor sends a signal indicative of the fluidic pressure to a tank level sensor module. The tank level sensor module receives the signal from the pressure sensor. A processor takes a series of pressure sensor signals over a sample window and calculates an average of the signals over a defined time window.
