KEL Liquid Differential Pressure Flow Meters From Kobold Instruments
The KEL Liquid Differential Pressure Flow Meters is designed specifically for applications in difficult environments. Metal housings, insensitivity to magnetic fields, and the ability to withstand large overpressures without damage, combine to make the KEL a tough performer. Designed with the industrial user in mind, the KEL Differential Pressure Flow Meters are easy to use, to read and to maintain.
Easy to Use
The KEL’s design addresses three key usage issues:
Easy to Read
All KEL Differential Pressure Flow Meters come with either 5:1 or 2:1 max:min flow turndown. The 5:1 meters are typically be used in wide range metering applications. The 2:1 units are used in process monitoring situations, or in any installation requiring reduced pressure loss (see flow vs. pressure loss table.) This specialization offers superior scale resolution to a one-size-fits-all approach.
To make the flow easy to read, the KEL Differential Pressure Flow Meters have a large 4½” dial face with the measurement units evenly spaced on it’s perimeter. This even spacing is possible since the meter movement is linear with flow. The internal mechanism that linearizes the flow also dampens out needle vibration, making it possible to truly read the flow rate, rather than guess at it.
Easy to Maintain
The orifice portion of the KEL Differential Pressure Flow Meters are connected to the pressure sensing section via ducts bored into the meter casing. Since the KEL requires no pulsation snubbers because of its built-in damping, these ducts are made large enough for easy cleaning. The larger ducts make the KEL less sensitive to fouling in the first place.
With costly downtime in mind, the brass and brass-cast iron wafer-style KELs allow the pressure sensing portion of the meter to be isolated from the orifice portion while the system is pressurized. This eliminates the need to interrupt the user’s process. An isolation mechanism makes sure that no valuable operating time need be lost to perform unscheduled sensor maintenance.
