Divesoft Professional Flow Limiter DIN W21.8-14

The Divesoft Professional Flow Limiter DIN W21.8-14 is a reduction valve piece for taking gas samples for analysis. Output cylindric connector W21.8-14 is connected to the Divesoft He/O2 Analyzer by a Connecting Hose (#1043). The screw connection to connect with the bottle is G 5/8" with 300 bars (other sizes are available on request). Output flow is constant 0.2 litres per minute, regardless of the pressure in the cylinder.

The benefit of the Divesoft Professional Flow Limiter DIN W21.8-14 is that it provides the low 0.2 l/min gas flow rate required for the Divesoft Hel/O2 Analyser to provide a continuous measurment of the gas contents. This is especially useful when you are gas blending with a Nitrox or Trimix stick.

The Divesoft Professional Flow Limiter DIN M26x2 includes a valve piece for lowering the pressure before unscrewing it from the tank. (The reduction valve piece can be ordered in different desired configuration.)

Flow limiters enable accurate gas sampling from scuba cylinder/tank to analyzer. The flow limiter is connected to the valve with DIN thread and then connected with Connecting Hose to analyzer. The flow is streamlined and measurement is accurate, comfortable and without gas lost as it in other analysers. Divesoft offer several types of flow limiters, including a flow limiter with a reduction valve included (Professional Flow Limiter).

What Is The Difference Between Flow Limiters?

Professional Flow Limiter is equipped with reduction valve and keeps constant flow rate independent on tank pressure. It is possible to analyze almost empty tanks with great comfort. It is suited for filling stations and continuous gas blending. Recommended by The Scuba Doctor.

Standard Flow Limiter is based on the nozzle principle and its flow rate varies with the pressure of gas in the scuba cylinder. Measurement takes longer if the cylinder is not full. It is suited for doing gas analysis after filling the cylinder and personal use.

Simple Flow Limiter (Still) is cheap, quick and practical alternative to the flow limiters above. The flow limitation is reached by carefully opening the valve. It is included with the stand-alone Divesoft He/O2 analyzer.

Inflator Flow Limiter is very practical in the moment when all gear is set up and we have to know the gas in the cylinder. We connect this flow limiter to the low pressure inflator hose and problem is solved.

NB. The connection hose #8009 has to be ordered separately
