3.4.5 Maximum pipework forces (end loadings)
Mass flowmeters have a maximum level of force (negative or positive) that can be applied to the
ends of the meter. Refer to the table below for permitted forces.
Maximum end loadings
• These (axial) loads have been calculated, based on 316L schedule 40 process pipework,
where un-radiographed butt welds have been used in pipe joints.
• The loads shown are the maximum permitted static load. If loads are cycling (between
tension and compression) these loads should be reduced. For advice, consult the
manufacturer.
