The EL4801 calorie computer is a digital instrument designed with the latest electronic technology to fulfill the demand for faster calorimetry. The EL4801 calculates the calorific value of natural gas or city gas using the sonic velocity measured by an ultrasonic flowmeter. This instrument is also capable of simultaneous flow rate calculation by the flow velocity measured with the ultrasonic flowmeter.
Densitometers are commonly used for calorimetry of city gas and natural gas that does not include inert gas by using the correlation between molecular weight (density) of the gas and calorific value. This calorie computer, however, calculates calorific value by utilizing the correlation between molecular weight and sonic velocity as well as the correlation between process temperature/pressure and calorific value as computational logic.
This calorie computer was co-developed with Osaka Gas Co., Ltd.
Note: This computer is a dedicated computer for the ultrasonic flowmeter of OVAL product.

In comparison with the previously offered instruments, substantial reduction in physical geometry, improved functions and ease of operation have been achieved. Included among the improvements in this newly developed instrument are simplified parameter changes and data logging with IC cards along with a large, easy-to-read LCD display.
This instrument receives density frequency signal from the density sensor and provides an analog output in proportion to the density of metered process fluid. In response to temperature and pressure signals, it also can provide an output corrected for reference conditions.

Using the most advanced electronic technologies, this digital instrument has been developed specifically to meet the most demanding fluid flow measurement applications where accuracy is the prime requirement.
In response to the flowrate and temperature information of fluid arriving from the sensing terminal, such as a flowmeter, it calculates fluid flow, reduced to the equivalent volume flow under standard conditions, and totalizes the flow.
In addition to meter error curve correction capabilities, a volumetric conversion factor as a quadratic function of temperature is introduced to implement density related weight conversion, giving you increased freedom to optimize compensated calculation.
An analog output and instant flowrate (corrected for meter error, temperature, and converted to mass) output are additional provisions.
With a model dedicated only to flow and pressure inputs, the instrument can also carry out calculations as a pressure compensator with fixed temperature value.
