A liquid level sensor system actuated by a column pressure includes a hollow member having a distal open end adapted to be positioned into a liquid reservoir to a depth below a liquid surface level, and a sensor head unit. The sensor head unit is responsive to the column pressure to provide an indication of a liquid level in the reservoir. A flow restrictor is positioned to dampen instantaneous differential column pressure changes presented to the bellows member while permitting steady state column pressure to be communicated to the bellows member.
