Product details

Instrument Overview

An indirect measurement device based on pressure sensors and air ducts, primarily used for water level monitoring. It indirectly measures the water level by detecting pressure changes generated as air bubbles rise within the air chamber. This device is applicable to monitoring activities at reservoirs, river channels, streams, canals, hydrological stations, oceanographic stations, pump-gate stations, hydropower stations, and other similar sites.

Product Features

(1) Water level measurement accuracy can reach 1 mm.

(2) Features automatic zero-point correction.

(3) Eliminate zero-drift errors

(4) Use a connecting-rod piston to reduce frictional damage to the piston seal.
