Measuring accuracy

Reference conditions

Medium: water

Temperature: +20°C / +68°F

Pressure: 1 bar / 14.5 psi

Maximum measuring error

Mass (standard)

Liquid (≥ 20:1 of nominal flow rate):
±

0.1% of actual measured flow rate (depending on the measuring sensor)

Liquid (< 20:1 of nominal flow rate):
±

zero point stability (depending on the measuring sensor)

Gas:
±

0.35% of actual measured flow rate ± zero point stability (depending on the

measuring sensor)

Mass (option)

Liquid (≥ 10:1 of nominal flow rate):
±

0.05% of actual measured flow rate (depending on the measuring sensor)

Current output electronics

5 µA

Repeatability

Liquid: ≤ 0.05% + zero point stability

Gas: ≤ 0.2% + zero point stability

Operating conditions

Temperature

Process temperature

Refer to technical data for the measuring sensor.

Ambient temperature

Depending on the version and combination of outputs.

It is a good idea to protect the signal converter from external heat sources such as

direct sunlight as higher temperatures reduce the life cycle of all electronic

components.

-40…+65°C / -40…+149°F

Stainless steel housing: -40…+60°C / -40…+140°F

Ambient temperatures below -25°C / -13°F may affect the readability of the display.
