Coriolis mass flow controller for low flow ranges

The recently released version of the Quantim from Flotech extends mass flow ranges for lquids and gases to as low a flow as 1g/hr, ideal for pilot and laboratory scale plants.

Flotech Solutions announces the second-generation Coriolis mass flow meter/controller with approval for use in Class 1 Division 2 installations as a UL-recognised component.

Since its original introduction, the Brooks Instrument family of Quantim Coriolis technologies has been recognised by numerous industry awards as an innovation in precision mass flow control for low-flow ranges.

This recently released version extends flow ranges to as low as 1g/hr and as high as 28,000g/hr.

"Quantim will now be available for installation in locations which are potentially hazardous, as defined by Class 1 Division 2," commented Steve Kannengieszer, director of industry marketing for the Brooks line of industrial technologies.

"In addition, the wider Quantim flow ranges extend the reach in all types of installations where precision mass flow measurement and control are required".

A modular hardware platform using improved sensing tube geometries and optical sensing techniques now enables Quantim to handle both liquids and gases.

Customers will also experience better overall accuracy at the low end of the flow range because of improved zero-stability.

The new Quantim Coriolis mass flow controller features a new valve that is more forgiving of variations in line pressures and reduces the chance of clogging due to the use of a larger orifice.

The new valve also uses an all-metal valve seat, thus eliminating potential control issues associated with elastomer valve seat compatibility and swelling.

Quantim is said to be the lowest flow Coriolis meter and controller available on the market today.

Users can change liquids or gases without switching meters or recalibrating the device.

Quantim has no moving parts in the area where process liquids and gases flow, which minimises maintenance requirements.

Minimal physical space is required due to its small, integrated design.

Piping and wiring during installation are dramatically simplified since Quantim has fully integrated sensor, transmitter, valve, and control electronics.
