ProductFeatures1. Bi-directional measurement, can measure the positive and negative, the net cumulative flow2. Automatic memory before 64 days prior 64 months, the first 5 years of light product flow rate3. Automatic memory 64 days before the working status of flow met er4. Auto memory the former 64 times more time and power flows can be manual or automatic inspection in order to reduce the flow losses5. Programmable volume (quantitative) Controller6. Configure GPRS / GSM module enables remote monitoring and control
