Accuracy / MPE (Maximum Permissible Error)

MPE according to OIML R49 / ISO4064

+/-2% Inrange Q2 ≤ Q < Q4; ±5 in range Q1 ≤ Q ≤ Q2

Metrology Data

Accuracy Class: 2 (according to 1504064 / OIML R49)

Metrological Class: D (according to 1504064 / OIML R49)

Range Q3/Q1: 250

Temperature Rating: T30

Mechanical Data

Environmental Class: B. Optional A

Electromagnetic Class: E1

Environmental Temp: 0~55°C(32~131°F)

Permissible Flow Temp: 0.1~60°C (32.2~140°F) for permanent and up to 85°C (185°F) for short term (<24hours). However, factory calibration is done at room temperature only

Pressure: PN16

Pressure Loss

The pressure loss of a flow sensor is proportional to the square on the flow : Δp = k x Q2

Here Δp is pressure loss, Q is volume flow rate and k is the coefficient.

All meters have Δp less than 0.63bar at Q3, meet ISO4064 / OIML R49 standard and AWWA standard.
