摘要
A system for determining rod position in a rod pumped well is described that includes a laser unit mounted on an underside of the walking beam and a reflector plate mounted on the sampson post of the rod pumped well in a position near the laser unit. The laser transmits a beam onto the reflector plate allowing the laser unit to determine the distance between the laser and the reflector plate. The distance between the laser and reflector plate as determined by the laser is transmitted to a controller which calculates the position of the rod in the rod pumped well based on the distance determined by the laser.
