SIBATA Digital Orifice Flow Meter OFD-1

SIBATA Digital Orifice Flow Meter OFD-1,The flowrate of high volume air samplers is calibrated using a standard flowmeter (roots meter). A roots meter is intended for installation, so it cannot calibrate flowrates at the measurement worksite.

The OFD-1 digital orifice flowmeter is an on-site measurement compatible flowrate calibrator for HV-500F/-500R/-700F/-700R/-1000F/-1000R/-RW high volume air samplers. Changing the conventional orifice flowmeter, which uses a U-shaped glass tube, to a sensor type, and adding an air pressure meter and thermometer means that when calibrating high volume air samplers, the values displayed can be used as is, without conversion by the user. In addition, the HV-R series of high volume air samplers can be calibrated automatically, enabling even easier, faster on-site flowrate calibration.

● A temperature sensor and atmospheric pressure sensor are built in, and the flowrate conversion is performed automatically.

● It connects to the HV-R series/HV-RW with a USB cable, and can perform calibration automatically.

● The orifice plates (2 types) are recognized automatically, eliminating attachment errors.

● Traceability can be obtained. (flowrate only)

● A separately available adapter is required to connect the OFD-1 to a high volume air sampler. Purchase a separate square adapter for the HV-1000F/-1000R/-700F/-700R/-RW. Purchase a separate round adapter for the HV-500F/-500R. (If you have the previous orifice flowmeter set, you can use the adapter included.),
