5.1.1. General operation of the Mass Flow

The MFM integrates a sensor for measuring the flow-rate. The measured
value for the mass flow-rate is transmitted to a remote device via an
analogue or a digital output (field bus).

Description of the system
5.1.2. General operation of the Mass Flow
Controller (MFC)
The MFC comprises:
• a sensor for measuring the mass flow-rate,
• control electronics,
• an actuating element: low-friction solenoid control valve with a
high response sensitivity.
5.2. Operation of an MFM or MFC sensor
• The integrated flow-rate sensors use the thermal measurement
process (anemometric and calorimetric) to measure the mass
flow-rate. The main components are a heating resistor and a
temperature probe. The gas which passes through the device
modifies the temperature difference measured between both
resistors.
• The thermal measurement principle allows the MFC to control the
required mass flow-rate completely independently of the pressure
and temperature fluctuations in the application concerned.
The damping of the output signal can be changed with the
"Mass Flow Communicator" (see chap. 10.1.3).
On the MFC types 8710, 8711, 8713, 8715, the
technology for the integrated sensor requires filters to be
fitted upstream of the product when highly soiled fluids are
present.

Fig. 1: Operating principle for the Mass Flow Controller
The control electronics compare the mass flow-rate (x) measured by
the integrated flow sensor with the mass flow-rate set-point value
(w) supplied to the MFC. The control electronics then calculate the
actuating variable (y) to be supplied to the solenoid valve to control
its opening. The flow-rate is either maintained at a constant value, or
modified to a predefined profile.
The control operates independently of fluctuations in pressure or
increases in the flow resistance which may be caused by soiling of the
filter. The rapidly responding solenoid valve and the sensor dynamics
define the overall responding time.
The measured value for the mass flow-rate is also transmitted (xout) to
a remote device via an analogue output or a digital output (field bus).

Description of the system
5.3.1. Control electronics
The control electronics:
• process the mass flow-rate set-point values and measured values,
• control the solenoid valve.
Set-point value
The set-point value (w) is either transmitted either by an analogue,
normalized input signal, or digitally via the serial interface or the field bus
interface. If the set-point value is supplied by analogue transmission,
the following assignments are applied:
Signal
range
4...20 mA 4 mA, w = 0 % 20 mA, w = 100 %
0...20 mA 0 mA, w = 0 % 20 mA, w = 100 %
0...5 V 0 V, w = 0 % 5 V, w = 100 %
0...10 V 0 V, w = 0 % 10 V, w = 100 %
For the control of a system where quick flow-rate changes are not
permitted, a ramp function can be activated. The settings for an
ascending and a descending set-point value can be set separately.
More detailed information on the ramp function and on all
other functions can be found in the software documentation
for the MFM / MFC.
Set-point associated

Set-point associated
with the range max.
Control settings
The initial control settings are set at the factory.
• Amplification factors:
After start-up, the controller operates with amplification factors
dependent on the loop properties. When the autotune function runs,
these are determined automatically. This function enables the control
settings to be optimized for the system's actual conditions.
• Control dynamics setting:
The device has a setting which can change the control dynamics
with the aid of the "Mass Flow Communicator" software
(see chap. 10.1.3). Its extreme effects are:
1. a very quick adjustment in which overshoots are possible. This
enables the controller to respond immediately to very low control
deviations, causing the control to be very turbulent,
2. a slower adjustment to the required flow-rate. If the system is less
dynamic, the behavior of the controller may be damped so that
minor fluctuations of the measured value or set-point value are
adjusted slowly.

Zero point shut-off
A zero point shut-off is integrated to ensure the sealing function of the
valve. This is activated if the following conditions occur at the same time:

If the zero point shut-off is active, the PWM signal is set to
0 % so that the valve is completely closed.
5.3.2. MFC solenoid valve
The solenoid valve used for an MFC is a direct-acting, normally closed
solenoid control valve.
The ND (nominal diameter) of the solenoid control valve is determined
by the required nominal flow-rate Q
process and the density of the operating fluid.
If the device is operated within the specified pressure range,
the solenoid valve also takes over the sealing function
together with the control function. Limitation: in the case
of special, hard seal materials, the seal function cannot be
ensured. In this case an additional shut-off valve may be
required.
