OPERATION

Waterra has designed the 

HS-2 Oil/Water Interface Tapes

 as lightweight, 

compact, oil/water interface measuring devices. They feature both enclosed 
reels with very narrow profiles and more traditional open reels. The HS-2 closed 
reel can carry up to 30 meters or 100 feet of flat tape. The HS-2 open reels can 
carry 50, 75 or 100 meters or 250 feet of flat tape.

The electronics module located in the hub of the unit contains the batteries, 
electronic circuit board, buzzer, light, and on/off membrane switch. 

The on/off switch has a built-in timer so that the unit will automatically turn 
itself off after three minutes. This feature is designed to extend battery life. 
When the HS-2 is turned on, the battery light will be illuminated continuously. 
Low batteries are indicated by a flashing signal from the battery light indicator.

When the HS-2 Interface probe contacts a hydrocarbon liquid, the buzzer will 
emit a continuous tone and the oil light will illuminate. When the probe contacts 
water, the buzzer will emit an intermittent tone and the water light will illumi-
nate. There is no sensitivity adjustment available for the HS-2 meter.

open reel — counter clockwise

The 

HS-2 open reel

 winds the flat tape 

back onto the reel by rotating the handle in 
the counter clockwise direction.

closed reel — clockwise

The 

HS-2 closed reel

 must be rotated in 

the clockwise direction to wind the tape 
back onto the reel. 

OPERATION

The flat tape on HS-2 open reels and HS-2 closed reels must always be wound 
back onto the reel by rotating the handle in the correct direction, however the 
direction of winding is not the same for both of these reel formats.

Winding the tape back onto the reel in the wrong direction will cause problems. 
Additionally it is important with both reel designs that the tape be spread evenly 
across the spool as it is wound back into the reel. This can be done by rocking 
the reel from side to side as the tape is being wound up.
