4. Overview
The PVS5120-series can have a standard or a large pump. At sea level, the
standard pump takes samples at 1.6 m/s (5.1 ft/s) for horizontal draws of 7.6 m
(25 ft), and the large pump takes samples at 2.2 m/s (7.1 ft/s) at 7.6 m (25 ft).
When sampling is initiated, liquid travels through the intake hose to the volume
control tube into the metering chamber. The amount of water taken is set
mechanically using the liquid sensing rod and the volume control tube, which
means sample accuracy is precise every time, usually within ±2% or ±2 ml.
Sample accuracy increases when you have set the volume control rod and
tested the collected sample at setup. Once the pre-set amount has been
reached, all excess liquid is purged from the system, and the sample is dropped
into a container.
