 The microcomputer CMK-02 Volume Corrector is supplied either from battery or from mains, and may be used in gas measuring systems where high measurement accuracy, reliability and servicing simplicity is required at competitive price.
The features of the CMK-02 corrector including the possibility of extending with additional measurements, enable to apply the device in measuring systems where, till now, it was necessary to use much more expensive flow computers. The device complies with domestic and European Union standards.
The CMK-02 Volume Corrector is the device operating in 3V technology, made with the use of double side surface mounting (SMT).

C421 Series Internal Valves |
|
Introduction
|
The C421 Series internal valves are designed with two outlets, bottom and side. The side outlet permits installing horizontal piping immediately adjacent to the tank without the need for extra pipe fittings. Primary use for the C421 Series is on bobtails and transports.
These units are designed as primary shutoff valves and to reduce the chance of uncontrolled product discharge in the event of an accident. Like all Fisher threaded internal valves, all C421 Series are suitable for both LP-Gas (propane) and ammonia, and comply with NFPA 58 requirements.
