An ultrasonic level sensor emits sound pulses toward the water surface and measures the time it takes for the echo to return, converting this distance into water level.

A level monitor is a device that continuously measures water depth in a sewer, manhole, or tank, often used to provide early warning of blockages and overflows.
A flow monitor is an instrument installed in a pipe or channel to measure flow rate and related parameters like depth and velocity over time.
A diurnal pattern is the repeatable daily variation in sewer flow caused by human activity, such as morning and evening peaks and lower nighttime flows.
Closed-channel flow occurs when a pipe runs full under pressure, such as in a force main or pressurized water line, where flow is usually measured with in-line meters.
Open-channel flow is water movement in a conduit that is not completely full and has a free surface exposed to the atmosphere, such as most gravity sewers and ditches.
