Sentinel Sewage Sampler

The Sentinel Sewage Sampler is a flow-through dipper-type automatic sampler. The clog-resistant dipper and exhaust system make the Sentinel ideal for use with all types of waste. An efficient, CFC-free, expansion-valve refrigeration system preserves sample. The Sentinel has been time-tested and field-proven in over three decades of use throughout the world. Information on its specifications are available.

HOW IT WORKS

Sewage or process wastewater flows into the integral sampling chamber through a 2" NPT inlet line at the rate of ten to fifty gallons/minute by either gravity or external pump. Representative samples are assured by through mixing of the liquid before it flows over an adjustable weir to waste through a 3" NPT exhaust line. A sampling dipper attached to an oscillating shaft is located in the sampling chamber. Responding to flowmeter signals or actuated by the sampler's internal timer, the dipper collects a precisely repeatable 25 ml sample from the flow in the sampling chamber. The dipper then returns to its raised position, depositing the sample in the composite container in the sample storage compartment. The sample is stored in a thermostatically controlled refrigeration compartment until removed by the operator. A non-contact switch turns the system off when the composite is complete.
