Younio Digital Valve Control Water Meter

Feature:

• No built-in battery,in normal times no need to add electricity
• Instant add electricity instant read,directly output digital signal(not pulse),electromechanical reading coincide,no accumulative error.
• The meters use the low-power design,m-bus communication modes,connection nonpolarity,construction and maintenance convenience.
• With high anti-light interence ability,can work normally exposed in the strong sunlight
• Can actively report the sensor breakdown information in order to avoid water disputes
• Through the control center can remote transmission control open and close the valve
• In order to prevent the valve stuck,the valve control meter with the valve warm-up function(timing carry on the warm-up actions)
