Peerless’ solutions for industrial measurement include a complete line of pressure, temperature, thickness, level and flow instrumentation. Our ever expanding line includes Lumetrics, one of the fastest growing names in instrumentation.

Whether it’s pressure gauges for oil refining, temperature measurement devices for chemical processing, or level measurement sensors for storage tanks, instruments are critical to prevent failure, enhance safety and maintain quality control in numerous industrial applications.

Monitoring and controlling processes is necessary in in-plant environments, laboratories, and engineering offices. Whether you’re a plant operator, engineer, or scientist, accurately measuring and testing is a critical function in your work.

Instrumentation can be installed anywhere in a system or process where there may be the likelihood of a change in either pressure, temperature, liquid level, flow rate, etc. or anywhere the system designer deems a necessary data point.

When implemented in applications where trending and predictive maintenance are performed, instrumentation provides key information to the operator/maintainer as to the condition of the system or process. For example, high pressure differential across a filter will indicate the need for cleaning or changing of filter elements. OR, minimal change in temperature from inlet to outlet of a heat exchanger might indicate a restriction in flow of the cooling/heating medium.

Instrumentation is imperative in any industry where pressures, temperatures, liquid levels, flow rates, etc. are required to evaluate systems and processes.

Case Study

Medical Tubing, Lumetrics Achieves 75% Labor Savings

Measuring-CaseStudy01 A prominent medical tubing manufacturer approached lumetrics with a need for a non-contact, waterless inspection system for their products. OptiGauge provided a system that simultaneously measured tube wall thickness, inner diameter, outer diameter, ovality and concentricity, and automatically downloaded test results to a central data storage system. OptiGauge was installed in a clean room environment, and provided highly accurate measurements in less time, with reduced operator error. OptiGauge can also be installed on their production line providing real-time measurement and feedback to the manufacturing process, without the need for multiple measurement systems and integration required between the different vendors' systems.
