1. The digital display meter controller US211M-A can display the instantaneous flow, flow unit is L / min(or GPM),
2. The digital display meter controller US211M-A can display the cumulative flow, unit is L(or US Gallon)
3. The digital display meter controller US211M-A can count and show the frequency of the flow sensor. The frequency is in right proportion of the water flow rate.
4. The digital display meter controller US211M-A can show the temperature sensor with the NTC50K sensor. But the whole set doesn't include the NTC50K sensor.
5. The digital display meter controller US211M-A can goes off alarm when the flow rate drops to the default lower limit.
This system uses the advanced single chip microcomputer technology, LCD dynamic display screen to display the state of new flow measurement and control instrument. Ultra-thin design, generous and beautiful. With small size, light weight, showing visual reading, clear, high reliability advantages, and a pulse output flow sensor and electromagnetic valve and other ancillary to form a flow control system.
Features of US211M Controller:
Ultra-thin design, flexible installation: suitable for a variety of models of assembly, easy to use.
The large white backlit LCD screen: beautiful, generous, to realize digital.
The use of ultra wide range of external power supply: to make it more widely used, more energy and a variety of models to connect.
