18 Product Recommendation Select the Product for the application High Accuracy is not achieved with microcells. Recommend Mechanical changes where needed. 18

19 Food Processing Flat bottom tank modified. Load Link H-Beam 19

20 Plastic Resin Reactor Resin Reactor Modified Support Load Link 20

21 Plastic Manufacturing Load Link Supports Reactors 21

22 Resin Reactor Resin Reactor Load Link Support Load Link 22

23 What Not To Do Load Link Misapplied Load Link Tank 23

24 Load Stand II Even distribution of the weight on the top of the stand. Direct vessel support to either foundation or structural member 24

25 Load Stand II Note the ground lead Note the vessel and support stiffeners. 25

26 Load Stand II Customers BMH Engineering Fuller Engineering Cementos Apasco CEMEX US Mix Hylsa 26

27 Installation Issues Prepare the tank to accept Load Cells or Microcells. Mechanical Changes May Be Required. Customer Must Understand the Requirements of a weighing System. Piping Requirements 27

28 Plastic Pellet Blending Mixer for blending plastic pellets Load Cells 28

29 Plastic Pellet Blending Cross Braces to isolate the feed bins 29

30 Plastic Pellet Blending Vertical braces stop the interaction between the tanks. These tanks feed the blenders. Motor and Drive part of the blender 30

31 Mircocells and Pipe Stainless Steel Pipe Leg Application Microcells 31

32 Pipe Leg Application Stainless Steel Pipe Legs Microcell 32

33 Microcells Horizontal Indoor tanks Controlled environment Microcells 33

34 Microcells Horizontal Indoor Environment Microcells 34

35 Microcells Stainless Steel Tank Microcell 35

36 Plastic Pellet Manufacturing Storage tanks for plastic pellets Microcells 36

37 Plastic Pellet Manufacturing Cross bracing created a 20% error. Bolts removed and holes enlarged. Bolts double nuts Micro cells 37

38 Plastics Pellet Manufacturing Insulation did not improve the performance. Microcells 38

39 Plastic Pellet Manufacturing Tanks free from one another. Gusset support. Possible? Microcells 39

40 Plastic Pellet Manufacturing Microcells Cross bracing 40

41 Calibration Issues Prepare the customer for proper Calibration. Material Movement. Suspended Weights. Step Calibration. Truck Load Calibration. 41

42 Calibration Calibration methods Weights 42

43 Calibration 20,000 lbs. weights Repeat Load and Unload 43

44 Flex Coupler Rubber Boot Alignment 44

45 Flex Coupler Flex Coupler 45

46 Expansion Joints Expansion Joints Heat Vacuum 46

47 In-Process Weighing Load discs Pre fab 47

48 In-Process Weighing Load Discs Steam Jacket 48

49 Summary Conveying the knowledge to our customers as to how to attain the information they need. We have to convey to the customer what will be required in his applications to meet his information requirements. Do not adjust accuracy to make a sale. 49

71 Calibration Tips Gain x 2 = counts per Mv Gain x 4 = = counts per Mv Gain x 16 = = counts per Mv 71

72 Calibration Tips Foil Gage sensors x16 KM Sensors x 2 or 4 default normally is x 2 72

73 Calibration Tips Load disc output = 360 MVS 360 x = SVS 360 x = Weigh ll 360 x = Increase by x 2 if using gain of 4 for the SVS and Weigh ll 73
