Daniel's provers allow adjustment according to specific conditions and can be used for calibration of flow meters of various sizes and in different flow conditions. The proverbs allow you to determine the starting point for specific measurement conditions (initial installation) in order to track changes in the flow meter error, make it possible to control the repeatability of measurements and the linearity of the flow meter characteristics to meet contractual requirements for commercial accounting.


Daniel Prouvers
Among the Daniel pruvers there are ball bi-directional and unidirectional pruvers and piston pruvers suitable for operation at low temperatures. They are used for calibration of measuring instruments at the place of operation under operating conditions of the environment.
