Pulse input is compatible with all flowmeters series COVOL, and with any instrument that
has an pulse output of one of the following types:
- De 0 a VCC, where VCC < 24V
- NPN open collector
- Potential free contact
Turbine input is compatible with all turbines series TM and with any instrument that has a
pickup type output with a voltage between 30 mVpp and 10 Vpp.
IMPORTANT NOTE: If the input pulse is chosen, the associated sensor must be
connected to terminals 1, 2 and 3, as indicated in section 3.2.2 on page 7. In the same
way, if turbine input is selected, the connection must performed at terminals 4 and 5 as in
section 3.2.3 on page 8.
6.5 Analog filter
The input signal can be filtered in order to cancel high frequency non desired signals.
6.4 Input
In this screen the type of signal from the sensor connected to the MT03F can be chosen.
For flowmeters series COVOL, a selection of 150 Hz filter is recommended.
For turbine flowmeters series TM, a selection of 1500 Hz filter is recommended.
6.6 Diagnosis
It allows to check some parameters of the equipment.
