PRESO gages indicate pressure differential (DP)
between two points. Flush and surface mounting
and portable kits are available for permanent
and field applications.
Flow rate is determined using the principle
that the difference in pressure is proportional
to the rate of flow in a pipe.
Both the lightweight GM portable kit, and the
GMD DirectReadout Meter are suitable for applications
including DP measurement across filters, heat
exchangers, backflow preventers, pipelines, ducts, etc.
Large dials feature a 270° arc for faster, more
accurate, read-outs. Precision-engineered, dust-tight,
casings ensure trouble-free operation.
