Flow Meter

Designing Flowmeters That Meet Testing Requirements

A New Industry Standard in Flowmeter Design

Liqua-Tech flowmeters meet stringent calibration and verification:

  • Our meters comply with factory testing requirements to +/- 0.08%–0.4% level of accuracy

  • Approved by the National Type Evaluation Program (NTEP)

  • Full compliance with Underwriters Laboratories

  • All parts compatible with pre-existing, non-Liqua-Tech installations

Available Models:

LPM-101


Designed for applications that require accurate recordings for fuel consumption and inventory control. Can be used for either high-pressure LP-gas liquid (350 psi) or lower-pressure refined fuel.

Rate of Flow:
• Low Range:1.66 to 5.0 GPM
• High Range: 3.0 to 18.0 GPM

Working Pressure:
• 350 psi (24 bar) max (24.6 kg/cm2)

Connections:
• 3/4" or 1" NPT companion flange

Operating Temperature:
• -10°F to 125°F
• -23°C to 52°C

Features the innovative Liqua-Tech measuring chamber, with hard-coated piston, special dense metal oxide finish, and hardened steel bearing shaft.

LPM-102


Designed for retail sales dispensing units, the LPM-102 offers the widest flow range available in a meter of this type.
• Vapor Eliminator
• Strainer
• Differential Valve
• Optional Trac-Bearing or Low-Flow Chamber
