Battery Operated Electromagnetic Flow Meter
Product Description
A battery-operated electromagnetic flow meter is an advanced device designed for measuring the flow rate of conductive liquids without the need for external power sources. These devices are especially beneficial in locations where power supply is limited or unavailable, such as remote water sources and temporary installations.
Product Features
- Micro power consumption design, five 3.6V lithium batteries, work continuously for 5-10 years and easy to replace.
- The liquid crystal display can display multiple flow parameters such as instantaneous flow rate, flow rate, cumulative total of forward and reverse directions, and alarm prompts.
- There are no moving and resistance parts in the measuring tube, almost no pressure loss, and can work reliably and continuously for a long time.
- The measurement range is wide, and the flow velocity measurement range is 0.05m/s~10m/s.
- Stable measurement, high measurement accuracy and strong anti-interference ability.
- It has the function of pulse output and GSM wireless data remote transmission.
- It has the function of data saving, which can save 1000 groups of flow data, which can be set arbitrarily and data query.
