2.3.5Flange types

The meter body is available with raised face or ring-type joint flange.

2.3.6Gas temperature range

The gas temperature ranges for the standard T-11, T-12, T-21 and T-22 transducers are as show in Table 2-2.

1. T-21 transducers use W-01 transformers

 

2. T-22 transducers use W-02 transformers

 

 

 

 

 

 

Temperatures below -20 °C may damage the transducers. In no-flow conditions for extended lengths of time or during meter storage, you should remove all transducer pairs if the temperature range is expected to exceed these limits.

Consult Daniel for higher temperature applications.

2.3.7Repeatability

Repeatability precision is ±0.2% of reading in the specified velocity range for SeniorSonicTM Meters.

2.3.8Accuracy limits

SeniorSonicTM accuracy limits typically are:

AGA 9 compliant

± 1% without a flow calibration (10” and smaller)

±0.7% without a flow calibration (for 12” and larger)

± 0.1% with a flow calibration

JuniorSonicTM accuracy limits typically are:

± 2% without a flow calibration
