5.1.4 Connection for sample intake and for version with sample pump
• Maximum suction height:
• Vacuum pump: standard 6 m (20 ft) option 8 m (26 ft)
• Peristaltic pump: standard 8 m (26 ft)
• Maximum hose length: 30 m (98 ft)
• Hose connection diameter
• Vacuum pump: 10 mm (3/8 in) 13 mm (1/2 in) , 16 mm (5/8 in) or 19 mm (3/4 in)
internal diameter
• Peristaltic pump: 10 mm (3/8 in) internal diameter
• Intake speed:
> 0.6 m/s (> 1.9 ft/s) for 10 mm (3/8 in) ID, as per Ö 5893, US EPA
> 0.5 m/s (> 1.6 ft/s) for ≤ 13 mm (1/2") ID, in accordance with EN 25667, ISO 5667
Note the following when erecting the device:
• Always lay the suction line so that it slopes upwards from the sampling point to the
sampler.
• The sampler must be located above the sampling point.
• Avoid siphoning effects in the suction line.
Requirements for the sampling point:
• Do not connect the suction line to pressurized systems.
• Use the suction filter to impede coarse and abrasive solids and solids which can cause
clogging.
• Immerse the suction line in the direction of flow.
• Take the sample at a representative point (turbulent flow, not directly at the bottom of the
channel).
Useful sampling accessories
Suction filter:
Impedes coarser solids and solids which can cause clogging.
5.1.5 Connection for sample intake on version with sampling assembly
• Minimum height difference (sampling assembly to suction line gland): 0.5 m (1.6 ft)
• Maximum hose length: 5 m (16 ft)
• Diameter of hose connection: 13 mm (1/2 in)
Note the following when erecting the device:
• Always lay the sample line so that it slopes downwards from the sampling point to the
sampler.
• The sampler must be located below the sampling point.
• Avoid siphoning effects in the suction line.
Requirements for the sampling point:
• Connect the sampling assembly to pressurized systems with max. 6 bar (87 psi).
• Avoid sampling points with bigger, abrasive solids that could clog the system.
• Take the sample at a representative point (make sure the suction line is completely
submerged).
