| titleOfInvention |
Versatile electronic surface level measurement sensor and surface level sensing method |
| abstract |
The present invention provides a surface or interface level of a material having a transceiver 12 and an inner conductor 21 of a coaxial cable 16 that electrically couples the transceiver 12 to a lead line 14 partially submerged in the material. Start the measuring sensor. A launch plate 18 is connected to the outer sheath 19 of the cable 16, and a resistor 20 connects the launch plate 18 to the induction zone 14. The launch plate 18 generates a reference pulse that is returned to the transceiver 12. Electromagnetic waves transmitted from the launch plate 18 propagate along the guide line 14. The electromagnetic waves are reflected at the surface or boundary and received by the launch plate 18 and transmitted to the transceiver 12 as reflected pulses. The transceiver 12 determines the surface or interface level for the launch plate 18 by measuring the time delay between the reference and reflected pulses. |
