HYDRO-D1900
NEW RANGE OF PORTABLE AUTOMATIC BUBBLE TO BUBBLE FLOW MEASUREMENT SENSORS AND EXTERNAL SENSORS IN OPEN CHANNELS AND MANIFOLDS
New portable flowmeters, low consumption, allowing level measurement by bubble or external sensors (ultrasound, radar, piezo, any 4-20 mA sensor)
bubble to bubble :
Thanks to its compact compressed air generator, the HYDRO D1900 range measures the level by means of that of the injection pressure of a low air flow at the foot of the water column.
This pressure is applied to a silicon membrane sensor which delivers a signal proportional to the water level.
External sensor :
Any external sensor with a 4-20 mA output signal images the level of the flow.
The Level is then converted into flow by a “Q(H) curve” defined by a parametric formula or by a set of pairs of points (H, Q). The filtered flow and the cumulative hourly volume (first 168 hours for each site) are stored in flash.
Declining :
HYDRO D1901 : 1 meter water height (full scale)
HYDRO D1905 : 5 meters water height (full scale)
