The Superb Zeta 5000 Gains MCERTS Approval.
Etr-Unidata announces that their superb Zeta 5000 gained MCERTS Approval in August 2008. With this new dust monitor process operators are are to look at the bigger picture!
Process Operators can now benefit from the innovative design of Etr-Unidata's new MCERTS Approved Zeta 5000 continuous dust monitor to make accurate, reliable and fast measurements that are not significantly influenced by such factors as stack moisture content, particle size distribution or variations in stack velocity.
David Curtis who is the Administrator of the Source Testing Association (The UK body established over 12 years ago to advance the science and practice of emission monitoring) considers the Zeta´s revolutionary approach as a significant step forward in providing a representative sampling area within the stack and could overcome limitations of some dust monitoring techniques.
Unlike conventional optical based dust monitors the revolution Zeta 5000 has its transmitter and receiver units located on the stack at an angle of 90 degrees to each other. The transmitter is designed to fire a powerful large cone shaped projection of light into the center of the stack, the receiver then picks up the light reflected from the particulates. This unique 90 degree configuration enables a much larger area of the stack to be monitored for particulates then with more traditional probe or cross duct methods. This increased area could typically exceed 25% of the total stack area compared with less then 1% for some other common techniques.
The increase stack area covered makes for a more representative measurement to be achieved. Accuracy of measurement is extremely important in compliance monitoring when very low emission limit values have been set by the enforcement authorities. In these situations process operators need to make reliable and consistent measurements
Etr-Unidata's Sales Director Cameron Stathers says that: "The Zeta 5000 is a significant new development in dust monitoring that can help them achieve this".
