K-BAR 2000B-WGF Series Multipoint Insertion Flow Meter

Brand: Kurz Instruments

K-BAR 2000B-WGF multipoint insertion flow meter is engineered specifically for wet stacks, condensing gas environments, and biogas applications.

The K-BAR WGF processes the dry flow signal independent of the effects of moisture in the process gas stream.

K-BAR 2000B-WGF flow meters have effectively no impact on the flow stream, proven high accuracy, and are highly economical for both initial and maintenance costs.
Features
  • Steel, 16 gauge (Type 4, IP65) polyester powder‐coated enclosure
  • Two optically-isolated loop-powered 4-20 mA outputs
  • One 4‐20 mA non‐isolated analog input
  • Two optically isolated solid‐state relays / alarms
  • Two digital inputs dedicated to purge or zero‐mid‐span drift check
  • Built-in zero-mid-span drift check
  • Velocity-dependent correction factors for flow rate
  • Built-in flow totalizers and elapsed time
  • User‐configurable digital filtering from 0 to 600 seconds
  • Configuration/data access via USB or RS-485 Modbus
  • Programmable for shifting flow profile distribution
  • 3-year warranty
  • Benefits:
    • The first multipoint thermal mass flow meter offering accurate and reliable wet gas flow measurement
    • Highly competitive with other flow measurement technologies in initial, setup, operation, and maintenance costs
    • Eliminates compromised flow data by ignoring fogging in the stack
    • Promotes better combustion monitoring by more accurately tracking the output
    • Ideal for wet stack, flue gas, and mine ventilation environments
    • Greenhouse gas emissions can be accurately reported
    • Reduce over-reporting of emissions caused by condensing moisture
