5.1.4 Connection for samplingfor version with pump
• Maximum suction height:
Vacuum pump: Standard 6 m (20 ft), 8 m (26 ft) optional
Peristaltic pump: standard 8 m (26 ft)
• Maximum hose length: 30 m (98 ft)
• Hose connection diameter:
Vacuum pump: 10 mm (3/8"), 13 mm (1/2"), 16 mm (5/8") or 19 mm (3/4") internal diameter
Peristaltic pump: internal diameter of 10 mm (3/8")
• Intake speed:
> 0.5 m/s (> 1.6 ft/s) for ≤ 13 mm (1/2") ID, as per EN 25667, ISO 5667
> 0.6 m/s (> 1.9 ft/s) for 10 mm (3/8") ID, in accordance with Ö 5893, US EPA
Note the following when mounting the sampler:
• Always route the suction line with an upward slope from the sampling point to the sampler
• The sampler should always be located above the sampling point
• Avoid siphoning effects in the suction line
The following conditions must be met at the sampling point:
• Do not connect the suction line to pressurized systems.
• Use a suction strainer to catch bigger, abrasive solids that could clog the system
• Immerse the intake hose in the direction of flow
• Take the sample at a representative point (turbulent flow, not directly at the base of the
channel).
Useful sampling accessories
• Suction strainer:
Catches bigger, abrasive solids that could clog the system.
• Immersion assembly:
The adjustable immersion assembly fixes the suction line to the sampling point.
5.1.5 Connection for sampling for version with sampling assembly
• Minimum height difference (sampling assembly to the gland of the suction line): 0.5 m
(1.6 ft)
• Maximum hose length: 5 m (16 ft)
• Hose connection diameter: 13 mm (1/2")
Note the following when mounting the sampler:
• Always route the suction line with a downward slope from the sampling point to the sampler
• The sampler should always be located below the sampling point
• Avoid siphoning effects in the suction line
The following conditions must be met at the sampling point:
• Connect the sampling assembly to pressurized systems with max. 6 bar
• Avoid sampling points with bigger, abrasive solids that could clog the system
• Take the sample at a representative point (ensure the pipe is completely full)
