Construction of the Jet Nozzle Set
The jet nozzle is made of stainless steel. Knurls on the circum-ference facilitate disassembly. This is useful for cleaning after the end of the test. The nozzle has an O-ring for sealing.
Behind it is the flow indicator, which operates on the variable annular gap principle: a float with a defined orifice moves over a tapered mandrel. The greater the flow, the further the float is moved. The counterforce is applied by a spring, so the display is practically independent of position.
A black ring on the spring-loaded float serves as the pointer. The red mark on the glass tube indicates the nominal flow rate. The two black marks serve as an aid for judging the deviation. They indicate deviations of about ± 10 % from the nominal flow rate.
The basic construction is shown in the photo on the title page. The valve is used to shut off and adjust the flow. The handpiece has a thermally insulating coating to keep the cold of the water away from the operator‘s hand.
Scope of delivery:
• Nozzle body with knurling
• Handpiece, inner diameter approx. 16 mm
• Flow meter, almost independent of position
