Product Overview
Description
Product Description
Features:
1.Clear LCD display screen, display instantaneous flow and cumulative flow respectively
2. High-strength piezoelectric crystal,integrated structure, impact resistance
3. Optional temperature compensation, pressure temperature, to meet more field services
4.The circuit board is processed through ageing before delivery, and it is with the real flow calibration for whole machine , more suitable for field use
5.No external power supply is required. It adopts 3.6V lithium batter for power supply, which can continuously work more than two years, especially suitable for use in the field where the power supply is difficult to access.
