Doppler Flow Meter
Full line system, providing the user with all possible flow functions:
- Flow Display
- Automatic Control
- Totalization
- Batching
- Recording
- Computer Interface
- Fault Alarm
Features
- Autajust™ - Automatically sets up and maintains proper operation
- Track Mount Clamp-On Transducers: Fast installation without shutdown; no liquid
contact or pressure drop
- Fault Alarm: Automatically monitors equipment and application, and alarms when
inoperative or zero flow conditions occur
- Wide Applicability: Same system operates on most pipes
- Separate Transducers: Excellent flow sensitivity, linearity and repeatability at
pipe temperatures up to 500°F
- Remote Transducer Location: Transducer cables up to 300 feet
Equipment Description
- Typical Series 180 system
- Consists of a set of two Model 181 transducers clamped to the pipe
- Separate Model 182C cables (up to 300 feet in length) couple the two (transmit
and receive) transducers to the Model 183 Flow Display Computer
Transducer Specifications
- Temperature - Standard: -40 to 107°C (-40 to 225°F)
- Pipe Types: ¾" O.D. and up. Wall thickness up to 1". Most
metals or sonically conductive plastics without sonically nonconductive linings or
coatings
Flow Display Computer Specifications
- Flow Range (Switchable)**: 0.1 to ± 40 feet / second; 0.1 to ± 4 feet / second
- Totalizer Update Rate: 10 counts / second (maximum)
- Outputs
Switchable Span: 0 to 4 and 0 to 40 ft / sec: 0 to 10V at 10K ohms minimum; 4 to 20
mA at 275 ohms maximum
- Pulse Rate: 125 pps / ft / sec (nominal)
- Power: 115 VAC, 50 / 60 Hz
