Installation
2.3 Adjusting the Bubble Rate
·
Set the River Line control valve to the “Close” position.
·
Attach the HS23QC (supplied as an option) to the HS40 Compact Test Port and immerse the HS23QC in a beaker of
water.
·
Allow up to 10 minutes for the bubble rate and differential regulator to stabilize.
·
Undo the bubble rate locking screw and adjust the bubble rate (to say 21 bubbles/min) The bubble rate at the Test
Port will indicate the expected River Line rate at the orifice. Nip up the lock screw and check the bubble rate again –
it may change slightly when the lock screw is done up.
CAUTION: ADJUSTMENT OF THE BUBBLE RATE HIGHER THAN
THE MAXIMUM 45 BPM WILL VOID THE MANUFACTURER WARRANTY ON THIS PRODUCT.
·
Disconnect the HS23QC from the HS40 Compact Test Port.
·
Rotate the River Line control valve from the “Close” position to the “Open” position to direct the bubbles from the
“Test Port” back to the “River Line”.
·
(Please note leaving the purge valve in the closed position for more than 30 seconds after removing the HS23QC
could expose the transducer element to excessive pressure, damaging the element)
