The product is exquisite in appearance, compact structure, low installation environment requirements and meets the needs of industrial and personal consumer users. It is a cost-effective residential ultrasonic water meter.
Features
- Industrial aesthetic design, exquisite appearance, compact structure, precise measurement.
- No moving parts, wear-free ultrasonic technology.
- Low initial flow, effectively reduces the measurement loss.
- Free positioning for installation without impacting its accuracy, especially for the sub-meter where need to be installed close to the wall.
- The special design to avoid the air inside the meter on the top.
- Easy maintenance, the cover of the water meter housing is fixed by a plastic buckle instead of screw.
- Be available for domestic cold water (T30/T50℃) service in 15mm and 20 mm diameters.
- Temperature inspection and low temperature alarm.
- IP 68 water-proof.
- Approved and certified under MID European standards and ISO 4064: 2014.
- Wide communication possibilities
