Q: What are the approximate conductivity levels for RO water, purified water, and deionized water?

For reference: Ultrapure water and deionized water can reach as low as 0.055 µS/cm; RO permeate typically ranges from 1 to 10 µS/cm; secondary industrial purified water is usually under 2 µS/cm; and tap water ranges from tens to hundreds of µS/cm.

Q: Is a straight pipe run required for installation?

No. The LD-S Electromagnetic Flow Meter features a specialized flow channel design that eliminates the need for the upstream and downstream straight pipe runs typically required by conventional electromagnetic flow meters, saving space in compact skid-mounted systems or areas with piping constraints.

Q: Can it measure temperature and pressure simultaneously?

Yes. The LD-S Electromagnetic Flow Meter features a built-in PT100 temperature sensor (standard) and an optional pressure sensor. A single meter provides flow rate, temperature, and pressure readings, resulting in fewer process connections, reduced wiring, and lower costs.

Question 1

What is the minimum conductivity that the electromagnetic flowmeter can measure?

Accepted Answer

Standard electromagnetic flowmeters generally require a medium conductivity above 5 µS/cm, though some models can handle 2 µS/cm. The LD-S model achieves a lower limit of ≥1 µS/cm through adaptive variable-frequency excitation and all-digital signal processing.

Question 2

Can it measure pure water, RO water, or deionized water?

Accepted Answer

It depends on the conductivity. LD-S Electromagnetic Flow Meter can stably measure RO (reverse osmosis) permeate (typically 1–10 µS/cm) and secondary industrial purified water (<2 µS/cm). For ultrapure water, EDI permeate, or DI (deionized) water with conductivity below 1 µS/cm, the electromagnetic principle is no longer suitable; turbine or ultrasonic flowmeters are recommended instead.

Question 3

What are the approximate conductivity levels for RO water, purified water, and deionized water?

Accepted Answer

For reference: Ultrapure water and deionized water can reach as low as 0.055 µS/cm; RO permeate typically ranges from 1 to 10 µS/cm; secondary industrial purified water is usually under 2 µS/cm; and tap water ranges from tens to hundreds of µS/cm.
