DHI’s new molbox1+ flow terminal offers lower uncertainties for gas flow calibration
Fluke Corporation, DH Instruments Division, announces a major update to its molbloc™/molbox™ gas flow calibration system. The new molbox1+ flow terminal enables flow calibration customers to achieve 0.125% uncertainty on flow measurements. A new molbloc/molbox system configuration, molbox 1-S, increases system rangeability without the need for vacuum pumps.

The molbox1+ flow terminal is the heart of the patented molbloc/molbox flow calibration system. It performs the data acquisition and processing functions necessary to determine the flow through a molbloc flow element that is connected to it. molbloc™ flow elements with different flow path sizes cover a wide variety of flow ranges. The molbloc-S flow element is a high precision transfer standard for gas flow calibration up to 5,000 slm.

The new molbox 1-S configuration makes it easier and less costly to perform high flow calibrations using molbloc-S flow elements. With molbox 1-S, each molbloc-S element can cover a wider range (10:0 range turndown) without requiring costly vacuum pumps. The system is viable for in-situ calibrations because it fits easily on a calibration cart.

DHI offers a full suite of software automation products and hardware accessories are available to complete the flow calibration system, including COMPASS® calibration assistance software, devices for unit-under-test control and readback.
