Flow Meters

The VUA-Series Low Flow Orifice Adapters feature a calibrated, critical sapphire orifice with liquid filled vacuum gauge, brass fittings and inline filter to adapt to Apex Instruments’ isokinetic source samplers for methods requiring low flow sampling. The adapters are used for VOST and Method 6-type sampling. Adapters include 1/2" male and 1/4" female brass quick connects to attach the isokinetic source sampler to the VOST VU-cords. Three adapters are offered to provide approximately 1/2, 1 and 2 liters per minute flow rates. The VUA-575 is used for Method 7C to provide the required flowrate between 400-500cc/min.
The OFM-Series Orifice Flow Meters all feature a calibrated, stainless steel critical orifice with two liquid-filled vacuum gauges and stainless steel inline filter. All fittings, including the orifice and filter, are made of stainless steel and include 1/4" tube fitting end connections. These adapters are used with vacuum pumps to provide constant sample flow rates. Orifice sizes range from 4 to 35 providing flow rates from 0.076 Lpm to 6.1 Lpm.
Apex Instruments offers the precision machined acrylic (KFR-Series), molded polycarbonate (KMR-Series), glass tube (KGS-Series), and electronic flowmeters for a variety of applications. Available in precision engineered sizes and scales for a variety of fluids. The millimeter reference or direct read scales can be specified to meet any requirements. NIST traceable calibration certificates are available.
