Differential Pressure Orifice Flow Meters
KOBOLD RCM differential pressure orifice flow meters are designed for industrial flow monitoring and measurement of compatible liquids and gases with a low to medium viscosity and a low solids content. They are also suitable for some steam measurement applications.
Rugged, Durable, and Reliable
The RCM features a rugged and compact metal construction with no moving parts to wear out. This delivers a longer service life, higher reliability, and much less maintenance.
Pulsation Snubbers to Decrease the Influence of Turbulent Flow
In liquid applications of 6 GPM and higher, pulsation snubbers are incorporated into the connecting pressure passages to produce smooth flow meter operation independent of pipeline turbulence, which ensures the retention of high accuracy for applications with a more challenging flow profile.
Fully Featured
The RCM delivers a capable and well-rounded device with high accuracy, a small size, low cost, minimal maintenance, and an increased resistance to accidental damage. It is optionally available with a 4–20 mA analog current output for interfacing with remote displays and controllers. Limit switches are also available to provide high and low limit signals. In addition, a 0–1000 Hz frequency output is available to drive frequency-based controllers and counters.
Other Differential Pressure Orifice Flow Meter Models
For even more rigorous applications for liquid applications, consider the KEL Heavy-Duty Differential Pressure Orifice Flow Meters or the KPL Series Orifice Plates paired with the PAD Heavy-Duty Industrial Differential Pressure Transmitter for liquid, gas, or steam flow measurement.
