Veeder-Root Sensor Application Guide <br />Groundwater Sensor <br />The Groundwater Sensor detects free hydrocarbon product on the water table in up to 20 feet deep monitoring <br />wells. Hydrocarbons in the C5 to C16 range trigger a Fuel alarm. Water table dropping below sensor triggers a <br />Water Out alarm. An open sensor triggers a Sensor Out alarm. <br />Table 18.
