65 Years of Expertise,
One Call Away
Why process engineers across the Northeast rely on Miller Energy, Inc. for the region's most demanding measurement, control, and automation challenges.
In the world of industrial process control, a pressure reading that drifts, a flow measurement that lags, or a control valve that fails to respond can cascade — quickly — from a minor process variation into lost production, off-spec product, or a safety incident. The instruments and controls that monitor and govern industrial processes are not accessories. They are the nervous system of modern manufacturing.
That is why, since 1958, plant engineers and instrumentation specialists across New Jersey, New York, Pennsylvania, Ohio, and beyond have turned to Miller Energy, Inc. — not just as a product supplier, but as a technical partner who understands both the instrumentation and the process it serves.
As a manufacturer's representative and stocking distributor, Miller Energy brings together the world's leading measurement and control brands, factory-trained application expertise, regional inventory, and hands-on service support — all through a single, trusted local partner headquartered in South Plainfield, NJ.
Process Instrumentation: Precision Across Every Variable
Industrial processes are governed by four fundamental variables: pressure, temperature, level, and flow. Miller Energy provides comprehensive measurement and control solutions for all four — through a curated portfolio of best-in-class instruments from principals.
For flow measurement alone, Miller Energy's team supports the full spectrum of technologies: magnetic flowmeters for conductive liquids in water and wastewater service, Coriolis meters for mass flow and density in pharmaceutical and chemical applications, vortex meters for steam and gas measurement in power generation, and mass flow controllers for precision gas dosing in semiconductor and specialty chemical processes.
The same breadth applies across pressure, temperature, and level — with product lines engineered to handle the harshest industrial environments, from cryogenic gas storage and high-temperature refinery service to hygienic pharmaceutical clean rooms and outdoor water utility infrastructure. And unlike a catalog distributor, Miller Energy's factory-trained field sales engineers bring genuine process knowledge to every specification — which means the first product recommendation is almost always the right one.
Control Valves & Valving: The Action Side of Process Control
Measurement tells you what is happening in your process. Control valves determine what happens next. Miller Energy's valving portfolio spans the full range of industrial flow control — from precision globe-style control valves for utility and process service, to high-performance rotary valves for chemical and petrochemical applications, to sanitary butterfly and diaphragm valves for food and pharmaceutical processes.
Miller Energy's mission is to provide high quality solutions at competitive prices to users of valving and instrumentation products for industry — staying current with the latest technology while continuing to implement proven solutions.
— Miller Energy, Inc. Mission StatementBeyond product supply, Miller Energy provides control valve sizing and selection support — a genuinely valuable service in a product category where a misspecified valve creates far more process problems than it solves. That engineering advisory capability is what makes Miller Energy a preferred partner rather than simply a catalog source.
Analytical & Data Acquisition: Intelligence for the Modern Plant
As industrial facilities modernize toward continuous monitoring, digital integration, and the Industrial Internet of Things (IIoT), the demand for analytical instruments and data acquisition systems has accelerated. Miller Energy's analytical portfolio addresses process measurement beyond the physical variables — covering dissolved oxygen, pH, conductivity, turbidity, gas detection, and multi-variable process analyzers for water treatment, pharmaceutical, and chemical applications.
The company also represents leading principals in wireless instrumentation and data acquisition — including WirelessHART solutions and HART communication tools — enabling facilities to extend measurement to difficult-to-wire locations, reduce installation costs, and integrate remote process data into existing plant control systems without a major infrastructure investment.
Gas detectors, intrinsically safe sensors, and signal conditioning devices round out a portfolio that supports not just measurement, but safe and compliant measurement in hazardous area classifications, regulated industries, and environmental monitoring applications.

Why Process Engineers Keep Coming Back to Miller Energy
Across seven vertical markets and thousands of installations throughout the Northeast and Mid-Atlantic, four qualities consistently define the Miller Energy customer experience:
Technical Depth
Factory-trained field sales engineers bring process knowledge and application expertise to every engagement — not just product catalogs. Every recommendation is grounded in real industrial experience.
Local Presence
Six regional offices from New Jersey to Ohio provide same-day application support, local inventory, and on-site service. When a process problem is urgent, distance is never the excuse.
Product Breadth
25+ best-in-class principals — including ABB, Yokogawa, WIKA, Bürkert, and MSA Safety — deliver a measurement and control solution for virtually every industrial application and service condition.
Proven Longevity
In operation since 1958, Miller Energy's 65+ year track record is a rare differentiator. In an industry where trust is everything, that history speaks for itself.
A Growing Regional Footprint
Miller Energy's most recent chapter reflects a company that is not standing still. Guided by a strategy of targeted regional growth, the company has expanded significantly — both in geographic reach and customer depth — ensuring that wherever a plant or facility is located across the Northeast and Mid-Atlantic, a knowledgeable application specialist is close by.
Today, Miller Energy operates from six regional offices — each staffed with local application engineers and stocking inventory to support fast-turn delivery and on-site service anywhere in the territory:
