摘要： Counting mechanism for a flow meter for measuring a stream of gas or liquid, provided with a rotational shaft which is driven in rotation by the stream to be measured, for example with the aid of a paddle wheel or a rotary piston, on which rotary shaft one or more counting wheels are arranged. Each counting wheel is divided along the circumference into a number of segments, a number of sensors being placed around the circumference of each counting wheel at a distance apart which is such that each of the sensors lies opposite a different segment of the counting wheel. The sensors transmit a different signal for some of the segments than for the other segments. The positioning of the sensors and the segments is such that each position of the counting wheel gives a different combination of signals transmitted by the sensors. Some of the segments are magnetic, while the other segments are non-magnetic, and the sensors are magnetic sensors.

摘要： Measuring device with a rotary piston gauge which is placed in a pressure chamber, which pressure chamber comprises a supply opening and a discharge opening, in which a slack flexible membrane divides the space in the pressure chamber in a first sub-space in which the inlet opening of the measuring module ends, and a second sub-space in which the discharge opening ends. The membrane forms a loop-shaped wall which envelopes the measuring module while leaving open the discharge opening of the measuring module, in which the extremities of the cylinder formed by the flexible wall are covered by means of a lid, in which the area enveloped by the wall and the lids ends in a passage opening. A feed-through pipe connects the passage opening with the supply opening of the pressure chamber. Both the supply opening and the discharge opening of the pressure chamber are provided with restrictions. The passage opening is arranged in one of either lids or in the flexible wall in the extension of the discharge pipe.

摘要： Measuring device for measuring the flow rate of a gas flow or liquid flow by means of a rotary piston device consisting of two rotary pistons which are placed in a pipe section and are mounted in such a way that they rotate about a rotary shaft, which rotary pistons are placed relative to each other and relative to the pipe section in such a way that by interaction with each other they shut off the pipe section.
During the rotation the two rotary pistons always remain in contact with the wall of the pipe section at one side and with each other at the other side, a quantity of gas or liquid being allowed through every turn.
The measuring device is characterized in that it consists of a number of parallel branches, with a rotary piston device accommodated in each branch, the rotary piston devices being synchronized with each other by means of synchronization means in such a way that the flow rate is approximately constant.摘要翻译： 用于通过由两个旋转活塞组成的旋转活塞装置测量气流或液流的流量的测量装置，该旋转活塞装置放置在管段中并且以这样的方式安装，使得它们围绕旋转轴旋转，该旋转活塞 活塞相对于管道部分相对放置，使得通过彼此相互作用，它们切断管部分。 在旋转期间，两个旋转活塞总是在一侧保持与管部分的壁接触并且在另一侧保持彼此接触，一定量的气体或液体被允许通过每一圈。 测量装置的特征在于它由多个平行的分支组成，其中旋转活塞装置容纳在每个分支中，旋转活塞装置通过同步装置彼此同步，使得流量大约为 不变。
