Temperature correction: As shown in example 3 of the principle of flow meters, the density of a gas changes with temperature.

A scale, for which 20°C is used as the standard, is used frequently for area (float type) fl ow meters in general.

We also manufacture standard fl ow meters calibrated in a thermostatic chamber.

However, calibration at 0°C or some other temperature may be necessary according to the operating condi-tions.

In such cases, we manufacture a conversion scale as shown in example 3.(The calibration temperature is indicated on standard tapered tubes.)
