Temperature Input - Badger Meter Impeller Data Industrial 3050 Series User Manual

Temperature Input

The Series 3050 BTU flow monitor can accept inputs from either a pair of thermistors or RTDs . The inputs are labeled T1 and
T2 . Since the T1 sensor is used to convert the volumetric flow (Example: GPM) to the mass flow (Example: Lbs/Hr) used in the
BTU calculations, the sensor connected to T1 should be in the same supply or return line as the flow sensor .
The temperature inputs of the flow monitor are extremely versatile . In addition to the factory default two-wire 10k @ 77° F
Type II Thermistors and three-wire 100 Ω platinum RTDs, the unit can be programmed in the field for a wide variety of custom
RTDs and thermistors . See the
with any custom inputs .
