A wastewater sampling system including: an inlet tube; an outlet port; a high-flow circuit fluidly coupling the inlet tube to the outlet port; a first pump, along the high-flow circuit, configured to pump wastewater through the high flow circuit; a sampling circuit, fluidly coupled to the high-flow circuit via a junction, comprising a solid waste filter fluidly coupled to the junction and a solid-phase extraction cartridge fluidly coupled to an outlet of the solid waste filter; a second pump along the sampling circuit; a controller configured to, during a sampling cycle at a first time, activate the first pump; at a second time, activate the second pump; and at a third time succeeding the second time by a sampling duration, deactivate the second pump.

Modular system for upstream wastewater sampling

A combined pressure and temperature sensing device includes a sensor port geometry that provides improved contact between a fluid media being measured and a thermistor cavity of the sensor port. The increased contact area provides improved response time and accuracy compared to previously known integrated pressure-temperature sensors. A temperature sensor element is offset from a pressure sensor element relative to a central axis of the temperature-pressure sensor body/package to facilitate substantially increasing a pressures sensor cavity volume without increasing the overall sensor port diameter. A wire-bondable thermistor support portion facilitates high volume automated production line. The temperature sensing element may be resistance welded to the thermistor support portion in a parallel manufacturing process.
