Siemens 200 Temperature Compensation P660 to P664, P654 Velocity at 20C, P660 Temp Source

P654 Velocity at 20°C

This value is used to automatically calculate Sound Velocity (P653).

Primary Index		Single Point Model		Dual Point Model
	Global			Transducer
Values	Range: 50.0 to 2000.0 m/s (164 to 6562 ft/s)
	•	P005 Units
Related	•	P651	Sound Velocity Calibration
	•	P653	Velocity

After performing a Sound Velocity Calibration, check this value to verify the acoustic beam atmosphere is air (344.1 m/s or 1129 ft/s).

Alternatively, if the acoustic beam atmosphere sound velocity at 20°C (68 °F) is known, and the sound velocity vs. temperature characteristics are similar to that of air, enter the sound velocity.

The units used are m/s if P005 = 1, 2, or 3 (or ft/s if P005 = 4 or 5).

The MultiRanger uses the TS-3 temperature sensor assigned to the transducer. If one is not connected, the ultrasonic/temperature transducer is used. If the transducer does not have an internal temperature sensor, the Temp Fixed (P661) value is used.

If the acoustic beam atmosphere temperature varies with distance from the transducer, connect a TS-3 Temperature Sensor and ultrasonic / temperature transducers, and select average.
