Caldon ultrasonic G3 wall mount transmitter
Precision feedwater measurement and megawatt recovery
Applications
- For nuclear feedwater and general purpose meters
Benefits
- Megawatts recovery
- Simplified electronics architecture for utilities that are not using the leading edge flow monitor (LEFM) system for a measurement uncertainty recapture (MUR) power uprate
Features
- Configured as a 4- or 8-path transmitter
- Operating temperature rating: 158 degF [70 degC]
- Meter pressure and resistance temperature detector (RTD) inputs
- Modbus®/TCP and RS-485 for digital communications
- 4- to 20-mA analog outputs for flow, temperature, or pressure
- Digital pulse (for fluid volume) and alarm status outputs
How it improves performance
The Caldon™ ultrasonic G3 wall mount transmitter measures feedwater mass flow to within 0.3% and temperature to within 0.6 degF [0.33 degC] when connected to the meter body. While frequently a subcomponent of the Caldon ultrasonic C3P system, it can be operated as a stand-alone transmitter. In conjunction with the meter body, it can be used to calibrate or correct existing plant flow measurement technology for lost megawatt recovery. This recovery takes advantage of the flowmeter’s immunity to the fouling or drift experienced by differential pressure flowmeters, which can result in reduced plant power output.
An integrated 400×240-pixel LCD displays system information, the meter’s indicated flow, totalized flow, fluid properties, and diagnostics data.
