Calcium reactor flow meter

[Silverfish]

Does anyone know if there is a Canadian distributor for Dwyer flow control meters or an equivalent? I saw a thread on rc that someone said they are an easy and accurate way to control co2 input to your calcium reactor. Apparently the flow control has a needle valve and measures co2 in cc/min, worth approx. $35 US. Better than a bubble counter so they say... I cannot for the life of me think of any local precision instrument companies. [img]images/smiles/icon_confused.gif[/img] [img]images/smiles/icon_confused.gif[/img]
