Page 3: Application
As a component of heat energy meter the SDU-1M flow sensor could by used for commercial account of energy quantity in district heating plants, in factories, in single or multi family houses. - Page 4 2.5.Table of default settings of the pulse value depending on the permanent flow rate and sensor size: Permanent flow q , m3/h Pulse value, liter/ pulse 0,02 0,02 0,05 0,05 Other pulse value settings could be selected according user needs by ordering the flow sensor. The pulse value is also indicated on the label of the flow sensor.

Remark: 1. LED indication begins when the button is pushed down. Status signals E (Error) and D (Direction) are passive signals and should be wired using the open drain output signal connection diagram such shown in 2.6.1 p. 2.8. When the measured flow rate exceeds maximal flow q per +10 %, the flow sensor transmits the amount of pulses which corresponds to the flow rate q +10 % and indicates corresponding... -
