FIELD: measuring equipment engineering, possible use for metrological provision of well geophysical equipment.
SUBSTANCE: device for calibrating well flow meters contains electric pump, damper, standard flow meter, measuring section, degassing device, computer. Measuring section is made in form of several pairs of vertically mounted sections of pipes of similar length and with internal diameters different for each pair, serially connected to one another. Degassing device is made in form of expansion vessel. In accordance to second variant, measuring section is made in form of one pair of vertically mounted and serially connected pipes of same length and similarly largest diameter.
EFFECT: increased trustworthiness of calibration results, provision of calibration process automation, increased reliability of structure.
