K-BAR 2000B-WGF Series Multipoint Insertion Flow Meter
Brand: Kurz InstrumentsK-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
