Methods and systems for a downhole sand level device

A well site includes a wellbore extending from a surface to a target reservoir. A production tubing extends into the wellbore from the surface. The production tubing forms a flow conduit from the target reservoir to the surface. A pump is coupled to the production tubing to lift well fluids to the surface. A sand level device is coupled below the pump. The level device includes one or more transmitters to generate and transmit at least two signals down the wellbore and one or more receivers to receive the at least two signals reflected from a reflecting surface in the wellbore. A time duration of transmitting and receiving the at least two signals may correspond to a straight-line distance between the sand level device and the reflecting surface in the wellbore. The sand level device is configured to send an alarm when the straight-line distance does not surpass a predetermined threshold.
