Communications tailored to the system’s topology
Deméter 1H communicates with a central server using GPRS technology or free-band radio and it can operate continuously for 6 months with no communications without losing any information.
Deméter, Hidroconta’s remote control device, is a fully autonomous system. Powered by a single lithium battery that provides a battery life greater than 3 years for the GPRS version and 10 years for the RADIO version (24 communications per day).
The Deméter 1H device is able to control one hydrant (water meter plus hydraulic valve) and a digital input.
This hardware developed by Hidroconta can function as a GPRS end-point
Designed for reed-type potential free contacts. 30 uA consumption with a closed contact. It can also be used with open collector-type pulse emitters (respecting the polarity).
Potential free contact. Similar to that described for the meter inputs. Useful when used with intrusion detection systems, digital pressure switches, etc.
- 2 10-bit resolution 0-20 / 4-20 mA analogue inputs.
- The device has a 15 Vdc terminal to power the sensors.
Solenoid valve outputs
Deméter 1H has 1 output for a 12 V latching solenoid valve. Triggering is performed using the energy stored in a 4700 uF capacitor charged to a voltage of 18 V. More than sufficient for most manufacturers.
- Deméter 1H is operated by a microcontroller with 256 KB of storage for firmware and 96 KB of volatile memory for program data.
- It also has external non-volatile memory with 244 KB to store records and settings. Enough to store over 20,000 records.
