Planning information Flowmax 30S
4 M I B
1. Planning information
1.1 Areas of application
The flowmeter Flowmax 30S is particularly suitable for the measurement of
dynamic processes of liquids in a pipe. It is used in beverage dispensing
systems
Its performance features are characterized by the following characteristics:
• no moving parts and therefore no wear
• high reproducibility
• easy cleaning
• safe against manipulation
• compact design
• integrated foam-/empty pipe detection
• excellent chemical resistance
1.2 Measuring principle
It usually takes more energy to swim against the flow than with the flow. The
ultrasonic flow measurement is based on the phase-difference approach:
Two ultrasonic-sensors located opposite from each other alternatively
transmitting and receiving ultrasonic signals. If there is no liquid flow both
sensors receive the transmitted ultrasonic signals in the same phase, i.e.
without phase difference. If liquid is flowing there is a phase shift. It differs when
measured in direction of the flow than when measured against the direction of
the flow. This phase difference is directly proportional to the flow rate.

1.3 Cleaning
Flowmax 30S has to be cleaned according technical Rules for beverage
dispensing systems TRSK 501“. While cleaning the Flowmax 30S is allowed to
stay in the pipe. The connections need not to be loosened.
1.4 Operational safety
Comprehensive self-tests ensure highest possible safety.
Faults (process or system errors) are output on a digital output or displayed on
the display menu.
The protection class is IP 65.
Flowmax 30S meets the general EMC immunity requirements according to CE,
EN 61000-6-3, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN
61000-4-6.
Flowmax 30S meets the safety requirements concerning the Protective Extra
Low Voltage directive according to EN 50178, SELV, PELV.
Attention: a max. wire length of 30m has to be complied!
For longer cables a special protection circuit is required!
2. Assembly and installation
2.1 Installation instructions
An arrow is printed on the nameplate on the front of the Flowmax 30S. The
measuring instrument must be mounted so that the product flows through it in
the direction of the arrow. For fastest possible gas detection it is important to
keep the pipe distance from tank to Flowmax 30S as short as possible.
Accurate measurement can only be guaranteed, if the pipe is completely filled
and if it is ensured that the liquid does not outgas.
Notwithstanding it may be advantageous for dosing applications to place the
Flowmax 30S as close as possible to the dosing valve, since tubes increase
their cross-section depending on the system pressure. This may lead to
repeatable differences.
Please note that it is absolutely necessary to have a back pressure of at
least 0.3 bar rel. (corresponds to 3 m water column) at the outlet of the
Flowmax 30S.
Solid matter particles that are carried along may result in measuring errors.
When using pumps, Flowmax 30S must be installed in flow direction behind the
pump, on the pressure side, in order to ensure sufficient pressure. Regard the
maximum pressure step of the Flowmax 30S.
For correct volume flow measurements straight and unobstructed inflow and
outflow zones for Flowmax 30S have to be observed. Starting from the
connection thread these have to be at least:
DN 7 DN 10 DN 15
inlet 5 cm 5 cm 40 cm
outlet 0 cm 0 cm 20 cm

2.2 Assembly of the flowmeter
In order to fasten the Flowmax 30S to a solid ground it has two bores with
female threads M4 at the front face (for dimensions see section 5, Technical
specifications). The housing of the DN15 version has additional bores on its
backside. Thus, the mounting to an existing construction is possible. Suitable
fixing material for the mounting, e.g. to a wall, can be delivered on demand.
To insulate all surfaces between the connector parts of the hydraulic pipes and
the Flowmax elastic gaskets, e.g. of PVC or silicone, should be used. The union
nuts must be tightly fastened.
2.3 Electrical wiring
Serious injury or death from electric shock may occur if wiring,
installation, disassembly or remove of wires is performed while electrical
power is energized.
Always shut off or disconnect electrical power at service panel and lock
switch or breaker and tag to prevent energizing electrical power during
work or while Flowmax 30S is not assembled and installed.
Wiring installation, disassembly and removal must be performed by
qualified persons experienced and knowledgeable about electrical work.
If the original plug is cut attention must be paid to connection polarity and
operating voltage!
Take care of the plug position when plugging it into the socket!

3. Commissioning
3.1 Operation
If Flowmax 30S is used as a flow meter in beverage dispensing systems, it does
not require any operation on site since the following parameters are in a factory
setting which ensures an optimum function. The Flowmax 30S can also be
supplied with customer-specific settings.
If necessary, this presetting can be changed individually using the integrated
interface. The external display and programming unit FlowCon 200i is required
for this purpose (see chapter 6, Accessories).
The following parameters may be changed to settings suitable for the individual
conditions:
Output O1 and O2
- pnp-logic
- npn-logic
Configuration output 1
- pulse output (pulse value)
Configuration output 2
- empty pipe alarm
(delay time, switching state with gas or empty pipe)
Creeping suppression
3.2 Functionalities of flowmeter and default settings
3.2.1 pnp-/ npn-logic
Here, a determination is made as to whether a positive signal (pnp) or a mass
signal (npn) is output at the outputs 1 or 2.
pnp-logic => the output switches to 24V, the LOW level is defined by the
master device. HIGH potential corresponds to the supply voltage.
npn-logic => the output switches to 0V, the HIGH level is defined by the master
device
bipolar (only for output 2) => the output switches both to HIGH (supply voltage)
and to LOW

output 2 : empty pipe alarm
npn-logic pnp-logic
Figure 3: outputs O1 and O2 are used in npn- and pnp-logic
Setting range: pnp-logic, npn-logic
Default setting: npn-logic
3.2.2 Configuration output 1
Output 1 can be used as a pulse or empty pipe alarm output. When pulse output is
selected, the pulse value can be set
Setting range: pulse output, empty pipe alarm
Default setting: pulse output
3.2.2.1 Pulse value
The pulse value determines the flow volumes for which an output pulse will be
emitted.
Choose a configuration which will neither exceed the maximum output
frequency of the Flowmax 30S (10kHz) nor the maximum input frequency of the
control. The pulse / pause ratio is 1:1. The pulse length is limited to 1s.
Exampel: 5.0 ml/pulse
This means: a pulse is output every 5.0 ml
Setting range: 0.1...3000 ml/pulse, in steps of 0.1 ml/pulse
Default setting: 1.0 ml/pulse

3.2.3 Output 2
Output 2 is used as line B for RS485 operation, and the vacant state of the
measuring channel can be signaled via the line
For the operation of the RS485 interface, the lines A and B are required, i.e.
output 2 can not be used as a switching output in this case.
Setting range: empty pipe alarm
Default setting: empty pipe alarm
3.2.4 Creeping suppression
The creeping suppression excludes flow measurements that result from
convection in a narrow band around zero, even with a closed valve. At the
factory, the creeping suppression is set at a standard value in relation to the
cross-section of the flowmeter.
Creeping suppression works with a hysteresis of - 25%.
Example: Creeping suppression = 5.0 ml/s
If the flow rate is lower than 3.75 ml/s the pulse output becomes
inactive. If the flow rate exceeds 5 ml/s a pulse is output again and
added to the totalizer.
Setting range: 0.0...400 ml/s, in 0.1 ml/s steps

3.4 General information
Please check the following before powering the flowmeter for the first time:
• Check the electrical connections and cable allocations.
• Check the installation position of the flowmeter. Is the direction of the arrow
on the housing/name plate and the actual flow direction in the pipe
congruent?
• Is the measurement pipe completely filled with fluid?
• Check the back pressure in the system.
When everything has been checked, switch on power. After 30 minutes with
power running the measuring device reaches the maximum accuracy.
