We have developed tools for servicing our flow meters, particularly the IP80 and TX80 Series. The mandrel, part no. 26117, is useful for holding any IP or TX with its rotor removed, while replacing a sensor. Made out of non-marring plastic, it can be screwed to any bench. The spanner, part no. 26118, is very useful for threading the sensor retaining screw in and out. (This job can be done with an ordinary screwdriver, but it is more difficult.) The photo on the right shows these tools being used.
