What are the support material (i.e. concrete base) flatness requirements for HI LPRA Load Point Assemblies and HI LPRC & LPRB Series Load Point Assemblies?

+ - what tolerance will I need to work with for the concrete floor / base or steel structure?  This is not the actual Load Cell, but the physical floor, concrete or steel structure that will carry the vessel, tank(s) etc.

There are several methods of leveling the load cell base plate. Attached is a drawing showing one such method.
The general precautions are as listed below and in the load cell installation manuals.

Site Preparation:
1. All mounting surfaces for the base and loading plate MUST be level. The distance between the mounting surface of the loading plate and base must within 1/32” of the nominal height. The Load Point Assemblies in a system must be level to within +/- 0.5 degrees. This means the floor base or steel structure where the load cells are located should be level to within +/- 0.5 degrees.

2. When mounting the base plate on concrete, use grout to level the plate.

3. Any welding should be done prior to installation of the load points.

4. Proper drainage should be provided to prevent the load point assembly from standing in water. The Advantage load cell will not be affected by standing water, but in-plant housekeeping would request a dry environment for safety.
