Density Measurement Instruments
JW Player goes here
Tracerco provide nucleonic density measurement instruments to a variety of industries. Each nucleonic density gauge or transmitter is designed to fit the clients vessel, pipe or process, using the smallest possible radioactive source (typically Cs-137), and the highest sensitivity detector. Variations in the radiation intensity due to tiny changes in density allow Tracerco to accurately and effectively measure the process in real-time. Each system is tailored to the client requirements, to ensure space is optimised and the reading is provided in a suitable format.
Tracerco's software (inside each density measurement instrument/detector) is the most advanced currently available, providing adaptive techniques to track process changes faster than any other system on the market, reducing noise, improving response and providing a solution using the smallest source size for worker safety.
The density measurement instrument product family allows:
- Ultra sensitive design enables highly accurate measurements with small source size
- Detectors tuned to the specific radiation source in use, and not susceptible to interference
- Real time external measurements without contact with the process
- Simplified design and construction, resulting in a dramatic saving to the customer
- Low maintenance and spare requirements due to the simplicity of design
- Both process wetted, and non-wetted (non-intrusive) possibilities
- Automatic source decay compensation
- Automatic pressure compensation
- Simple two-wire or three-wire communications wiring
- Zones 0, 1 and 2 use - Intrinsically Safe
- HART, Modbus, Foundation Fieldbus options
- Measurements can be provided of: Oils, emulsions, foams, water, sand, condensates, liquids, solids, rag layers, middlings and many other process variables.
