The helically sprung measuring body is displaced in the flow chamber. The reed contact acts as a control device. It is arranged outside the flow chamber, and responds to the transducer. The cylindrical measuring body (5) supports the transducer (7). It has a support or attachment on the conical end (4) as a guide; the other end is connected to a helical spring (6) which is fixed to a part of the lid or housing. The transducer (7) acts on several reed contacts.</p> |
