Description
Product characteristics:
Drip measurement-the starting flow rate is low, about 3L/H
Wide range ratio-the range can reach R**0
Unique flow channel design-the design of flow channel is unique,
and the rectification performance is good, so as to ensure the flow
rate precision, the supports are easy for installation to ensure
the uniformity of the products.
Healthy and environmental protection- the water meter case adopts
corrosion resistant stainless steel, healthy, environmental
protection and can be reused.
Other functional characteristics:
(1)Ultrasound flow rate measurement, correct calculation
(2)No mechanical parts for the flow channel, no abrasion and with
long service life
(3)Adopting M-bus interface, which can realize remote automatic
meter reading and is convenient for centralized management
(4)Point out counter-flow for counter installation, and the flow
rate will not be accumulated.
(5)Can store accumulated flow rate of the recent *4 months
(6)Installation mode: horizontal or vertical(water flow direction
must be the same as the water meter arrow)
