Why Pressure & Temperature Compensation required for Orifice Flow Meters ?
When we derived a formula for predicting flow rate from pressure dropped by a  orifice or venturi tube or, we had

Several standards exist for orifice pressure tap locations. Ideally, the upstream pressure tap will detect fluid pressure at a point
