Measuring Chamber
One reason for the superb performance of Liqua-Tech meters is our superior measuring chamber with original hard coated piston, with special dense metal oxide finish and a hardened steel bearing shaft. Liqua-Tech was the first to introduce these innovations. In addition, the Liqua-Tech measuring chamber is available with the patented TRAC-BEARING® roller for sustained accuracy, reliability and lower maintenance.
Soft-Seal Differential Valve
Another innovation is Liqua-Tech's soft seat differential valve that incorporates an o-ring-to-metal seat for a positive seal. The standard metal-to-metal seating of competitive models is prone to leaking.
Ductile Iron Meter Housings
Instead of following the competition's trend toward aluminum housings for ease of machining, Liqua-Tech has continued to use durable, resilient ductile iron. Our ductile iron meter housing are a more stable metal and handle temperature fluctuations better than aluminum, which tends to warp at temperature extremes. This ensures "flatness" where the measuring chamber seats, in turn maintaining accuracy. An additional advantage of using ductile iron is the resistance to stripped threads, a common problem in routine maintenance on aluminum meters.
