FE921 Handheld UItrasonic Flow Meter
Summary:
Handheld ultrasonic flow meters are used to measure the flow rate and heat content of various single-phase, homogeneous liquids that can transmit ultrasonic waves. These meters employ non-contact measurement, offer a wide measurement range, have no moving mechanical parts, and are unaffected by system pressure or harsh environmental conditions. They have been successfully applied in the metering of fluids such as water, ultrapure water, seawater, wastewater, chemical process liquids, river water, and fuel oil. Handheld ultrasonic energy meters are widely used for measuring energy consumption in systems across industries such as refrigeration, heating, heat exchangers, chillers, and boilers.

Detailed introduction
Product Features
- High-precision measurement, with measurement accuracy better than, linearity better than, and repeatability better than
- Non-contact measurement: simply attach the magnetic ultrasonic flow sensor to the outer wall of the pipe to complete the measurement.
- Wide measurement range: by selecting sensors of different models, flow measurement can be achieved for pipelines ranging from DN15 to DN6000.
- Charging power supply: built-in high-capacity Ni-MH rechargeable battery, capable of supporting continuous operation of the flow meter for 10 hours.
- Large-screen LCD display showing instantaneous flow rate, cumulative flow, and flow velocity on the same screen
- Sensor signal interface requires no wiring—plug and play.
