Fuel flowmeter MU-VZO for diesel engines
|
Our company produces a flowmeter of own construction for fuel consumption measurement in diesel engines of maximal capacity 250 L/h.
They are used in fleet management systems. At present over 400 of such flowmeters are successfully operating.
The first units were installed 5 years ago and they are still fully operational. Since then, the construction was enhanced and carefully tested.

The construction of our flowmeter is based on a Swiss mechanical flowmeter.
The measurement accuracy is equal to +/-1% and the accuracy of whole flowmeter system is equal to +/-1.5% excluding the effect of temperature.
The fuel flowrate is measured on the system inlet. Fuel from engine circulates in the flowmeter system.
A system of valves and a special tank eliminate the possibility of faulty measurements. Moreover the tank works as a heat exchanger, which eliminates, to some extent, the measurement errors which results from fuel temperature difference on the inlet and outlet of the system.
Due to the fact that mechanical flowmeters are prone to any impurities the system is equipped with special filters. Moreover the tank is equipped with a degasser which prevents engine from sucking air. Also there exist a possibility of installation of additional temperature probe in the tank for system temperature compensation.
The flowmeter may be used in fleet management systems (GPS),
counting terminals and others. It uses a 230 V magnetic (reed) pulse system output.
The flowmeter system should be installed as it is shown in below scheme.
Due to the degasser it is recommended to install the flowmeter system in vertical position. It is equipped with a resistant to hard environmental condition housing and mounting holes for fast and simple installation.
