Description
Двигатель 1 через зубчатую пару 2 приводит во вращение ролик 3 и перемещает относительно осветителей 4, 5 и 6 и фотоэлементов 7, 8 и 9 ленту 10, разматываемую с ролика 11. В этот момент регистратор 12 не сосчитывает импульсов, генерируемых фотоэлементом & от перфорации дорожки I-I. Когда прерыватель 13, имитирующий работу первого детектора расходомериой установки, затемн ет фотоэлемент 8, начинаетс счет j импульсов регистратором 12. Счет импулысов прекращаетс в тот момент, когда прерыватель 14 дорожки 1Н - 111 , имитирующий работу второго детектора расходомерной установки, затемнеет фотоэлемент 7. Таким ., образом, на регистратор 12 заранее подаетс известное количествь импульсов в услови х, эквивалентных услови м расходомерной .Установки .Motor 1, through gear pair 2, rotates roller 3 and moves relative to illuminators 4, 5 and 6 and photo cells 7, 8 and 9 the tape 10 unwound from roller 11. At this moment, recorder 12 does not count pulses generated by photo cell & from perforation track i-i. When the interrupter 13, which simulates the operation of the first detector by the flow meter of the installation, darkens the photocell 8, the counting of j pulses by the recorder 12 begins. .. Thus, the recorder 12 is supplied with a known number of pulses under conditions equivalent to the conditions of the flow meter. Installations.
Погрещность отсчетного устройства on- , JQ редел етс как разность между количеством отверстий дорожки 1-1 на участке между прерывател ми 13 и 14, сосчитанных визуально , и количеством импульсов, сосчитанных регистратором 12,25The on-, JQ readout device is defined as the difference between the number of holes in track 1-1 between the breakers 13 and 14 counted visually and the number of pulses counted by the recorder 12.25
Наличие перфорированной ленты 10 с дву м дополнительными дорожками и размещекными на них прерывател ми 13 и 14 расщи- р ют возможности применени прибора. Например , такой прибор может найти щиоокое зо применение при оценке метрологических свойствThe presence of perforated tape 10 with two additional tracks and the interrupters 13 and 14 placed on them expands the possibilities of using the device. For example, such a device can be used for evaluating metrological properties.
отсчетной аппаратуры поршневых расходомерных установок, положение поршн которых определ етс двум и более детекторами.readout equipment of piston flow meters, the position of the piston of which is determined by two or more detectors.
