Proline Promass 80 PROFIBUS PA

Technical data

91

Calculation example for gas:

• Sensor  type:  Promass F, DN 50
• Gas: air with a density of 60.3 kg/m³ (at 20 °C and 50 bar)
• Measuring range (liquid): 70000 kg/h
• x = 90 (for Promass F DN 50)

Max. possible full scale value:
g

max(G)

 = 

g

max(F)

 · 

ρ

(G)

 ÷ x [kg/m³] = 70000 kg/h · 60.3 kg/m³ ÷ 90 kg/m³ = 46900 kg/h

Recommended full scale values

See information on 

→ Page 101 ff. ("Limiting flow")

Operable flow range

Greater than 1000 : 1. Flows above the preset full scale value do not overload the amplifier, i.e. 
totalizer values are registered correctly.

Input signal

Status input (auxiliary input):

U = 3 to 30 V DC, R

i

 = 5 k

Ω, galvanically isolated.

Configurable for: positive zero return, error message reset, zero point adjustment start, batching 
start/stop (optional), totalizer reset for batching (optional).
