on each load cell in the case of the present invention usually weight which can then be summed to determine the wob as noted when an injector is in use uneven loading on the injector can occur meaning that the load on one load cell is not the same as load on another load cell in the case of the present invention it would not be uncommon for the injector to be slightly canted such that the weight on the load cells on one end of the beams would be greater than the weight on the load cells on the opposite end of the beams in prior art coiled tubing injectors it was common to use a single load cell in an attempt to measure wob however because there are so many other forces primarily from the guide arch and or the coiled being guided thereby a single load cell will not provide an accurate wob in the present invention there are at least two load cells and they are positioned between the injector mount and the injector such that any force exerted by the guide arch and or the coil tubing is detected and accounted for by the summing computer for example assume as is shown in the preferred embodiments there are four load cells in a generally rectangular pattern as per the embodiments described above if it is now assumed that there is 1000 lbs acting directly in the middle of the rectangle defined by the four load cells each of the load cells will see 250 lbs if the injector is now pulled 45 u00b0 in the direction of the guide arch the top.
