Delta-Elektrogas OM Measuring Orifices

In the complex environment of industrial combustion, accurate flow data is the foundation of energy efficiency. The OM series functions based on the differential pressure principle; as gas or air passes through the precisely machined opening of the orifice, a pressure drop is created. By measuring this drop via the integrated pressure taps, technicians can calculate the exact flow rate according to standard flow equations.

What distinguishes the Delta-Elektrogas OM Measuring Orifices from standard plates is their high-quality construction and factory-calibrated precision. Each unit is designed to be installed in a “wafer” configuration, fitting snugly between standard pipe flanges without the need for extensive pipe modifications. The orifice disc is made from durable stainless steel to resist corrosion and erosion from high-velocity gas streams, while the body—available in aluminum or steel—ensures long-term structural integrity. By implementing these measuring orifices, industrial plants can achieve a much higher degree of control over their thermal processes, leading to reduced fuel consumption and more stable flame characteristics.
