This calorimeter is a fixed gas calorimeter in a flame-proof enclosure (explosion-proof class: Ex dⅡB+H2 T4) designed for continuous, fast-response measurement of the "Calorific value," "Density," and "WOBBE index" of various fuel gases such as natural gas, coke oven gas, blast furnace gas, converter gas, biomass gas, and biogas.

This calorimeter is a fixed gas calorimeter in a flame-proof enclosure (explosion-proof class: Ex dⅡB+H2 T4) designed for continuous, fast-response measurement of the "Calorific value," "Density," and "WOBBE index" of various fuel gases such as natural gas, coke oven gas, blast furnace gas, converter gas, biomass gas, and biogas. The types of fuel gases that can be measured depend on the specifications. For information on the types of gases that can be measured by the product, check the "Measuring gas specification sheet" provided with it.

The calorimeter measures the speeds of "light" and "sound" that travel through the measuring gas by using an "optical sensor" and a "sonic sensor" and applying the Opt-Sonic calculation processing* to the measuring result. This enables the high-accuracy measurement of "Calorific value" and "Density" of fuel gases containing interference gases such as nitrogen and carbon dioxide.
The calorimeter can be used with minimum equipment even under constraint conditions with its high evironmental resistance.
The calorimeter, having an advanced self-monitoring/diagnostic function compliant with NAMUR NE107(self-monitoring/diagnostic of field devices), offers functions for performing real-time status monitoring for devices and informing abnormal statuses and maintenance requests with LCD display and contact output.
The calorimeter has a log data auto-save function that records the history of "operation statuses" and "self-diagnostic results" for a year or longer. Furthermore, another function provides outputting the log data via IrDA communication, which can be used for high-quality maintenance/follow-up services. (Optional services)
The calorimeter forms a "complete stand-alone unit structure" that consists of standardized units. Even if any malfunction occurs, quick repair and recovery can be achieved just by replacing a faulty unit on site.
