LP-07-I is a Level sensor that continuously detects liquid level. The resolution for measurement is 1 cm. (Resolution 1 cm.) By changing the resistance. (While the float is moving). Available in both selection thread and flange mounting. Because LP-07-I has a Resistance Transmitter that converts the resistance to 4-20 mA installed inside. So the output is 4-20 mA, which changes every 1 cm.
