Your benefits
- Conversion of an impulse signal to a Namur signal (4 - 20 mA / 0 - 20 mA):
High resolution for instantaneous flow rate indication (m3/h) in combination with the FM-1D/K - Can be retrofitted without damaging the calibration seal:
Easy and fast on-site installation
Applications
- Flow direction recognition (forward or backflow) by means of different signal levels
- Pulse transferral for forward and backward totalisation in combination with FM-1D/K
- Pulse output for process measuring, control and dosing functions
Properties
- Two different pulse values available (OD 01 or OD 03)
- Flow direction detection
- Flood proof (IP68)
- Cable length 3 m
