Because weighing is a non-contact method of measuring level, there is no chance of contamination. No matter what your mix of ingredients, weighing can measure:
Hardy's instrumentation ranges from blind transmitters to digital weight controllers. They can be connected to host computers, programmable logic controllers (PLCs), or Distributed Control Systems (DCS). Total net weight can be viewed or transmitted. Bar graphs, lights, and other large indicators are often used for long-distance viewing.
In addition to level measurement, the instrumentation can also control the filling and dispensing of the storage vessel. To weigh a storage vessel, it must be supported entirely by load cells. For example, a silo would have a load point assembly (load cell & mounting hardware) under each leg. A frame is constructed to transfer the weight of a skirted silo to three or more load points. Some vessels can also be hung in tension to save valuable production space.
Horizontal storage tank saddles are retrofitted with load points to accommodate vessel expansion and contraction with changes in temperature.
Hardy's C2® electronic calibration, eliminates costly scale calibration fees, especially on large storage vessels. C2 allows you to electronically calibrate even with the material in your vessel. With large systems, this feature can pay for itself in just one calibration cycle.
