Flow Limiter shows no output
If your Flow Limiter does not produce any gas output during measurement, follow the steps below.
Possible causes
-
Blocked nozzle or internal orifice
-
Closed output nozzle
-
Damaged internal components
What to try
-
Visually inspect the inlet and outlet for any visible obstruction.
-
Confirm flow limiter output. The standard flow rate (0.2–0.4 L/min) may not be audible. Connect a sampling hose and place the other end into a glass of water. Look for a slow but steady stream of bubbles.
-
Check whether the nozzle can be rotated freely to open (anti-clockwise) and close (clockwise).
Professional Flow Limiter
-
The nozzle can be rotated up to approximately 1.5 turns.
-
During normal use, only about a quarter turn is required to switch between measuring, pressure release, and closed modes.
-
Do NOT use excessive force. Rotating the nozzle beyond its limit may result in internal damage.
Basic Flow Limiter
-
The nozzle rotation range is approximately 2–3 turns from closed to full flow.
-
The output flow directly corresponds to the nozzle position. Adjust the flow by turning the nozzle accordingly.
Do not disassemble the Professional Flow Limiter. Unauthorized disassembly may result in internal damage and loss of warranty.
