1.2.2 Temperature

The LevelVent and AquaVent record temperature compensated water levels. Groundwater and surface water temperature measurements are particularly important in situations where temperatures may fluctuate significantly, and when temperature is used in determining liquid level, viscosity and hydraulic conductivity. Temperature monitoring is vital in the calculation of certain temperature dependent contaminant reaction rates. A Platinum Resistance Temperature Detector is used to accurately compensate for temperature changes within the range of 0 to +50ºC. The LevelVent and AquaVent will record temperature in the thermal range of -20 to +80ºC, but outside the range, compensation will be less accurate.
