Digitermo DTL DN20 M-Bus Ultrasonic Heat Meter
The Digitermo DTL DN20 ultrasonic heat meter is designed for heat energy measurement in central heating and cooling systems. With wired M-Bus communication, an LCD display and remote-reading support, it makes tracking energy consumption easy.
| The Digitermo DTL DN20 model is an ultrasonic heat energy meter with no moving measuring parts, used in central heating and cooling installations. It helps monitor heat energy consumption and transmits data to building automation and remote meter-reading applications via wired M-Bus communication. Total heating and cooling energy, instantaneous energy, temperature values, temperature difference and flow information can be displayed on the multifunction LCD screen. Menus can be navigated via the touch key. The DTL DN20 model stands out with a brass body suitable for horizontal or vertical installation, a replaceable 18505 B size battery and the ability to display historical period data. Nominal diameter, flow range, connection size and installation conditions should be the basis for technical selection. |
| Ultrasonic technology: No moving measuring parts in flow measurement. M-Bus communication: Offers wired communication suitable for daily and hourly remote reading. Heating and cooling: The LCD screen shows heating and cooling energy indices in separate menus. LCD and control: A long press on the touch key switches between different menu pages; temperature, flow, energy, operating hours and fault alarm information can be displayed. Battery and installation: Replaceable 18505 B size battery, stated battery life of up to 6 years; horizontal and vertical installation; brass body. Data history: The device menu states that 12 months of historical period data is displayed. |
