Designed for use in systems rated up to 15,000 psi (1035 bar), the JVHS gear meters are durable, accurate, and safe in high pressure environments. The JVHS series all can be hydro tested to 1.5 times the working pressure rating. The JVHS meters, constructed of 316 stainless steel with Xylan® coated steel bolts, come equipped with medium-pressure autoclave connections. These units are for use in high pressure hydraulic and fuel systems; in offshore chemical injection systems including methanol, corrosion and wax inhibitors; or in water treatment chemical-injection systems

  • Affordable & Accurate: This meter has the ability to maintain consistent accuracy despite changing viscosity conditions* , with accuracy of +0.5% of reading.
  • Rugged Construction: The JVHS’s solid body construction is made of 316 stainless steel for corrosion resistance and durability.
  • Flexible Meter: may be used in applications requiring bidirectional flow, and can be hydro tested to 1.5x the working pressure rating.
  • Hazardous Environment: Ready A complete line of explosion-proof sensors and displays are available for the JVHS meters.
