PCT enables wide gas flow rates controlled by one single instrument
14 Aug 2019
Remarkably improved near zero flow measurements ensure that PCT’s Alicat mass flowmeters and controllers are now able to read down to a single count.
This becomes impressive, says Premier Control Technologies (PCT), when considering that the full scale equates to 32,000 counts. In practical terms, however, it is worth operating at turn-down ratios nearer to 10,000:1.
Other features of the product range also benefit the user. For example, 50ms control response maintains tight process control. Mass and volumetric flow, pressure and temperature can be measured/output with all but temperature being controlled.
One hundred and thirty-plus gases are selectable via the menu with the stated accuracy remaining valid regardless of gas type or mixture. This eliminates conversion factors.
