Pressure sensor for a vapor recovery system

Pressure sensor for a vapor recovery system

A pressure sensor includes a pair of inputs for determining the pressure within a vapor recovery path. The inputs are positioned about a flow restrictor within the vapor recovery path. The vapor recovery path may include a mounting platform for attaching the pressure sensor and positioning the input...

description A pressure sensor includes a pair of inputs for determining the pressure within a vapor recovery path. The inputs are positioned about a flow restrictor within the vapor recovery path. The vapor recovery path may include a mounting platform for attaching the pressure sensor and positioning the inputs relative to the flow restrictor. In one embodiment, a vapor sensor may also be positioned within the vapor recovery path. An inlet port and an outlet port direct vapor from the vapor recovery path to a sensor. The inlet and outlet ports are positioned relative to the flow restrictor for forcing the vapor through the sensor. In this embodiment, a common flow restrictor within the vapor recovery path may accommodate both the vapor sensor and the pressure sensor. If vapor is not being returned in the vapor return path properly, the fuel dispenser may set an alarm condition and/or shut down the fuel dispenser operation. If vapor is not being returned at the proper rate, the vapor pump speed may be adjusted, for example, to bring the vapor return rate to the proper level.
