Proservo NMS83
Endress+Hauser
Hybrid tank measurement system (HTMS)
HTMS uses level and pressure measurements to calculate the contents of the tank and
(optionally) the density of the medium.
In non-atmospheric (i.e. pressurized) tanks it is recommended to use the HTMS
P1+P3 mode. Two pressure sensors are required in this case. In atmospheric (i.e.
unpressurized) tanks the HTMS P1 with only one pressure sensor is sufficient.

1. Navigate to Setup → Advanced setup → Application → Tank configuration → Level
2. Go to Level source (→  171) and specify from which device the level is obtained.
3. Navigate to Setup → Advanced setup → Application → Tank configuration → Pressure
→ P1 (bottom) source
4. Go to P1 (bottom) source (→  245) and specify from which device the bottom
pressure (P1) is obtained.
5. If a top pressure transmitter (P3) is connected:
Go to P3 (top) source (→  247) and specify from which device the bottom
pressure (P1) is obtained.
6. Navigate to: Setup → Advanced setup → Application → Tank calculation → HTMS
7. Go to HTMS mode (→  263) and specify the HTMS mode.
8. Use the other parameters of the HTMS submenu to configure the calculation. For a
