Bi-Generators Flow Meter of Instant Values (Characteriograph)

The article describes a variant of constructing an instantaneous flowmeter, designed to monitor the energy characteristics of internal combustion engines located on long-term bench tests, under different load conditions. The result of the development is a system using the method of indirect control of the weight of consumed fuel from a sample tank, by measuring the pressure in it. To ensure the required accuracy and stability, the flowmeter uses a pressure-period frequency converter built on a bi-ge­nerator circuit. As a result of the research carried out in the work: the algorithm of work and the functional scheme of the automated device intended for precision control of instantaneous fuel consumption are developed; the method of calculation of the basic metrological parameters of the flowmeter of instantaneous values is proposed; conducted research is the basis for designing new automa­ted devices for precision consumption control.
