On the name plate of the rotary meter the cyclic volume can be given in two possible formats:

with two digits behind the comma as stated in table 2 and 3, or
with a number containing 6 significant digits. In this case a HF pulse value can be accurately derived from the spinning rotors with an optical sensor.

** The EMR-Dual can be delivered as a low pressure $ \left( P_{\mathrm{m a x}}=2 1 \mathrm{b a r} \right) $ or a high pressure $ \left( P_{\mathrm{m a x}}=1 0 1 \mathrm{b a r} \right) $ variant.
