Transit time Ultrasonic water meter for heat measurement and water
flow Stainless steel
Description:
Bi-directional Ultrasonic water meter are for bulk volumetric flow
measurement. It can measure instantaneous flow and accumulated flow
from two directions. IP68 protection. The UFM has multi line LCD
display and key panel. This is widely used in municipal water
supply, water resource management, industrial water supply,
agriculture, irrigation and gardening.
Features
