STAFF GAUGE
GENERAL

The staff gauges allowed the direct reading of water levels by an observer and the record accuracy check of water level recorders.

Generally made of enamel steel, they are graduated for centimetric readings.

Two main types of staff gauges :

1)  with the metric and decimetric values engraved on each unit,

2)  with the decimetric values engraved on the units, but the metric values engraved on separate small plates which have to be fixed on the staff gauge units.
 
 

MEASUREMENT SPECIFICATIONS

The staff gauges have to be fixed vertically against bridge embankments or piers, or against strong steel bars stuck in the ground. The successive staff gauge units should be correctly levelled to allow accurate water level readings without « blank » or overlapping.
 
 

TECHNICAL SPECIFICATIONS

Made of enamel steel, clearly graduated each centimetre.
