High-Quality Propane Measuring Instruments at Your Disposal


Liqua-Tech's oscillating-piston meters are less costly to purchase and easier to maintain than other styles of meters. The design has been field proven in thousands of installations internationally.


Liqua-Tech prides itself on precision manufacturing. Our quality is attributable to the precision standards maintained in our machining processes. 100% inspection on all metering components ensure that every product manufactured by Liqua-Tech Corporation conforms to exact tolerances. LPM-102 and LPM-200 meters and components comply with Underwriters Laboratories requirements.


Liqua-Tech flowmeters and replacement measuring chambers meet stringent calibration and verification requirements. Our flowmeters comply with factory testing requirements to ±0.08% -0.4% level of accuracy. Liqua-Tech LPM-102 and LPM-200 LPG flowmeters have been evaluated under the National Type Evaluation Program (NTEP) and were found to comply with the applicable technical requirements of Handbook 44 "Specifications, Tolerances and Other Technical Requirements for Weighing and Measuring Devices".


Our staff is highly trained and well respected throughout the industry. From ordering to troubleshooting, customer service is a top priority. With our on-site technical support, special order items are usually available. We work closely with our customers to provide products to meet their specific marketing requirements and applications.

Pricing and Availability

Liqua-Tech offers our distributors and end-users very competitive pricing and shorter lead times. Quantity discounts are available. Parts traditionally ship within 24 hours of receipt of purchase orders. In emergencies, we can drop-ship directly to an end user and there is never an up charge or reduced discount for expedited service from Liqua-Tech.


Liqua-Tech markets our products through a domestic and international network of stocking warehouse distributors. Authorized distributors maintain facilities and an adequate parts inventory to perform warranty service claims and repair requirements. Our continued success is based on long standing relationships with these distributors, who rely on Liqua-Tech's delivery of quality products on time and at a competitive price.

Product Innovations

Liqua-Tech is constantly striving to improve the reliability and accuracy of our parts and meters.
Our industry trendsetting product innovations include.....

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.

Liqua-Tech meters utilize an innovative single piece stainless thermowell, reducing the chance of leakage. Competitive meters use two-piece units.

ATC Components
While other meter manufacturers have gone to plastic construction of ATC ratchet arms to reduce production costs, Liqua-Tech has continued to produce ours from more durable metal components.

Gear Trains
Liqua-Tech's higher quality gear trains utilize extensive use of bushings for increased longevity and improved accuracy.
