Easy-to-install, low-cost measurement of the small flows found throughout plant metering, operations, and research.
The integral orifice is a flow meter close-coupled with a differential pressure transmitter to make a complete flow meter for small lines. It can be ordered with internal NPT threads or flanged pipe runs welded both upstream and downstream of the flow restriction.
The orifice assembly mounts directly to the transmitter — flat gasketed surfaces bolt to the transmitter or a 3-valve manifold — or remotely with an adapter kit. Construction materials conform to NACE Standard MR-0175 (process-wetted materials).
Calibrated accuracy is ±0.5% of actual flow within the calibrated range; uncalibrated bores run from ±1.5% to ±5% of rate depending on bore size.
Send line size, service conditions, and materials — if you'd like us to calculate the bore, just include your flow conditions.
