Welcome to Procon Engineering's dedicated calibration site outlining details of our tried and tested force calibration system. We calibrate 1000's of vessels each year for clients across a broad spectrum of industries using ForceCal, and our systems are suitable for vessels up to 40 tonne capacity. One of ForceCal's key benefits is that in most applications, calibration can be carried out without the need to empty the vessel. The calibration procedure takes only a few minutes, thereby causing minimum disruption to your process.
