A new source of natural gas is the collection of methane that accumulates in landfills. Methane accumulation is the result of the natural decay of organic materials that are part of the landfill. Conventional natural gas wells are thousands of feet deep and produce gas at very high pressures. The methane gas in landfills occurs at much lower pressures – from just a few inches of water to a few psi.
If a large water main is leaking, how would you know? What part of the city consumes the most water, and when? These are questions often asked of the city water engineer. In order to give an accurate answer, direct measurement of the flow in a large water main is often the best way to verify metering station data. How can the flow in a water main be observed directly?
SUPPORTING INDUSTRIAL ENERGY AND ONSITE UTILITY SINCE 1970
What makes Validyne and the Utility industry a perfect fit?
Low Pressure Transmitters
Validyne pressure sensors and pressure transmitters have been used in the Industrial Energy and Onsite Utility industry for over 45 years. The VR technology used in our pressure sensors allows us to measure really low pressures very accurately over a wide temperature band. With full scales as low as 0.1” H2O we have ultra-low pressure transmitters available in a variety of form factors and certifications to meet your needs. Having worked with our customers we have developed over 3000 custom specifications that is very cost effective to our users.

Validyne products most prevalent in the Industrial Energy and Onsite Utility Industry
DR800 Draft Range Trasmitter
The Validyne Model DR800 Draft Range Transmitter is designed exclusively for very low pressure measurement needs. It has a “true” full-scale range as low as ±0.25” H2O, making it ideal for air flow control applications. It can be turned down to ±0.1” H2O; higher full-scale ranges to ±100” H2O are available. The DR800 offers 0.5% accuracy and an operating temperature range of -20°F to +185°F. The total combined temperature effects are less than 3%/100°F.
Validyne’s P532 Pressure Transmitters are ideally suited for measuring extremely low liquid and gas pressures in industrial applications. Full-scale differential pressure ranges from 0.10″ H2O to 2″ H2O with line pressure rating of 100 psig, ranges of 2″ H2O to 3200 psid with line pressures up to 3200 psig and ranges of 8 psid to 10000 psid with line pressures up to 10000 psig are offered. Gauge pressure ranges start at 0.10″ H2O and absolute pressure from 0.08 psia full-scale. The P532 Assembly includes the appropriate sensor, a pressure manifold assembly (which serves to isolate the sensor from external mounting and plumbing stresses), and an all solid-state electronics module housed in a moisture-proof, dust-resistant NEMA 4 enclosure.
The P55 withstands shock and vibration that can damage or even destroy other differential pressure transmitters in its class. With variable reluctance sensing technology, the P55 delivers fast dynamic response, high resistance to vibration and superior signal stability through ambient temperature change for a wide variety of low-pressure measurements. The P55 will accept both liquids and gases directly at the sensing diaphragm – and there are no internal isolation fluids to slow the sensor response or cause excessive temperature drift errors. Available in 410 SS, 310 SS, Inconel and Hastelloy.
The P365 transducer is designed to make low differential pressure measurements at high static line pressures. The P365 is ideal for flow or pressure drop measurements in high pressure hydraulic systems. Its compact design and rugged construction allow it to be used in harsh environments.
The DP303 is a true bidirectional, “Wet-Wet” differential pressure sensor designed for applications where very low differential pressures are to be measured in fluid systems involving high line, or working, pressures up to 5000 psig.
The P61 is designed for a wide variety of low pressure measurements where high resistance to vibration and superior stability through temperature change is required. The P61 will accept both liquids and gases directly at the sensing diaphragm. The P61 provides USB digital readings directly in engineering units.
