Paddle Flow Monitor Model: PSR-.. / PSE-.. Operating Instructions
4. Regulation Use
Series PSR and PSE are used to monitor liquid flow. Instruments are provided with an adjustable limit switch. Only low viscosity fluids that are compatible with the material combination chosen are allowed to be monitored. If using higher viscous media, large deviations in the specified switching range will occur. The instruments are relatively insensitive to dirt, however large particles may block the paddle, leading to erroneous alarm conditions; likewise, ferritic particles may deposit on the magnet and lead to faulty operation. In case of doubt, please contact the manufacturer.
PSR/PSE
5. Operating Principle
The KOBOLD flow monitors of series PSE and PSR are used where economical, reliable flow monitors are indicated. Depending on the flow velocity respectively flow rate, the baffle plate is deflected and moves the permanent magnet via the balance arm into the switching range of the reed contact mounted outside of the flow media. The flat spring, which also serves as a support for the balance arm, forces the baffle plate back to its rest position when there is no flow. KOBOLD baffle plate flow monitors are supplied completely assembled with fitting up to nominal size 40, or for larger nominal pipe sizes - supplied without a pipe length for direct insertion into standard T pieces or fittings. The sealing takes place via PTFE tape.
6. Use in Hazardous Areas (PSx-2)
6.1. General
The paddle flow switch, being a mechanical component, has no inherent potential ignition source. The mounted contact is suitable for usage in Ex-zone IIC and I as an intrinsically safe component.
The measurement units can be used as follows: In the Zone 0 (Gas-Ex, Cat. 1G) into explosion-group of IIA, IIB and IIC In the Zone 20 (Dust-Ex, Cat. 1D) In the Zone 2 (Gas-Ex, Cat. 3G) into explosion group of IIA, IIB and IIC In the Zone 22 (Dust-Ex, Category 3D) In the Zone 1 (Gas-Ex, Cat. 2G) into explosion group of IIA, IIB and IIC In the Zone 21 (Dust-Ex, Category 2D) In hazardous areas 1 and 2 in underground mining (category M1 and M2) Regulation usage does not cause any zone inside the fitting or at paddle. Exceptions are possible during start-up and shut-down of the plant.
PSR/PSE
The medium temperature limit area is fixed as follows:
6.2. Notes
The following points must be observed when using in hazardous area:
• The notes in every operating manual that is provided by the manufacturer must be strictly observed.
• Fixed parts (eg due to frost or corrosion) may not be solved by force in an explosive atmosphere present.
• Mechanical elements must be cleaned according to the conditions on site.
• The unit must be protected against external strikes.
• To ensure explosion protection, electrical and additional equipment must comply with the requirements of applicable local zones and must be examined separately by the installer of the machine / plant.
• It must be ensured that the device is included in the potential equalization.
• It is particularly important to ensure that no stray currents (due to engines that are operated with frequency inverters, welding machines and / or corrosion protection equipment) are performed on the devices.
• Direct dangerous electrostatic discharge to the resource should be avoided
• The device may only be exposed to small vibrations
• Freezing up of the device must be avoided.

6.3. Electrical Contact
The paddle flow switch can directly switch intrinsically safe circuits in Ex-zone or may be used in intrinsically safe current circuits in combination with a certified switching amplifier. The electrical connection is explained in chapter 8 “Electrical Connection”.
6.4. Potential equalisation
The all metal flow meters are to be incorporated in potential equalization system of the plant. This is achieved via metallic connection pipe.
PSR/PSE
6.5. Electro-Static
The devices are to be protected against electrostatic unloading. The case of the device is to be earthed electro-statically (for example with metal pipes). Besides, the local potential balance is to be established according to local regulations.
The wires must be protected in the installation in the hazardous area “0” against electro-static unloading. This can be done by using conducting pipes and rigid covers.
6.6. Ultraviolet radiation
The instruments incl. cables should be protected against radiation.
6.7. Propagating brush discharge
In dust Ex-areas propagating brush discharges should be avoided on the plastic parts and cables.
PSR/PSE
7. Mechanical Connection
Before installation
Please check that the actual flow matches with the
switching range of the instrument.
Ensure that the allowable maximum operating
pressure and operating temperature of the instruments will not be exceeded.
Remove all transport packing and be sure that no
packing material is left in the instrument.
The instrument may be installed in any position
(except PSR-..32 / PSR-..40 - for horizontal installation only); however, the top half of the paddle switch must be vertically positioned in relation to the pipe axis, and the arrow on the threaded fitting must match the flow direction.
For dirty media, it is recommended that the upper housing will be installed as
close to vertical as possible, respectively with not more than 40° deviation from vertical. This will prevent dirt from being deposited in the upper housing. When this is not possible, we recommend the instrument to be cleaned more frequently (see maintenance).
The application of PTFE tape or similar sealant to the connection threads is
recommended.
Check that the connection threads of the pipe are fully sealed.
Attention! Make sure that the supply voltage to the instrument conforms to the value stated on the equipment label. For higher power loads, we recommend our contact protection relay model MSR-10.
The inlet and outlet section needs to be minimum 5 x DN in front of and after the flow meter.
PSR/PSE
8. Electrical Connection
Ensure that the electrical supply lines are powerless. Connect the connection cable with your supply cable. The contact housing is made of glass-fibre reinforced plastic.
It is insulated in accordance with VDI 0720 Class II; separate insulation measures are not necessary.
After connecting the external equipment, the instrument is ready for operation.
9. Limit Switches
brown
black
red
The instrument is supplied with an adjustable contact. The standard contact, depending on the adjustments can be used either as N/O or N/C switch. The instrument is supplied ex works as a normally open contact. Optionally, the PSR/PSE can be ordered with an SPDT switch.
Contact mode
Depending on the positioning of the adjustable standard switch, the following contact modes are available.
Normally open
The contact closes when the flow increases and the set point value is reached or exceeded. The switch opens again with falling flow at the minimum value based on the switch hysteresis.
Normally closed
The contact opens when the flow increases and the set point value is reached or exceeded. The switch closes again with falling flow at the minimum value based on the switch hysteresis.
Option: Changeover (SPDT) contact
The normally open and normally closed switch modes are simultaneously available from the same position. When retrofitting the standard design with an SPDT switch, the upper switch housing must be replaced at the same time.
PSR/PSE
Switch Point Adjustment
When adjusting the switch point, the clamp plate in the top of the upper housing must be loosened, enabling the switching unit to be repositioned. For ease of adjustment, the switching unit is marked with a white and a red arrow. The front edge of the clamp plate serves as the adjustment marker.
Normally open contact
(standard setting, as shipped)
The switch range is adjustable in the area of the red arrow. By sliding the switching unit in the direction of flow, the minimum switching value given in the table is achieved. By sliding the switching unit in the opposite direction, the maximum listed switch value is achieved.
Normally closed contact
The switch range is adjustable in the area of the white arrow. By sliding the switch unit in the direction of flow, the minimum switch value given in the table is achieved. By sliding the switch unit in the opposite direction, the maximum listed switch value is achieved.
Option: Changeover contact
The following options for wiring apply:
Black and brown conductor = contact opens at decreasing flow. Black and red conductor = contact closes at decreasing flow.
After successful adjustment, tighten the clamp plate by means of the screws.
Hysteresis
The Hysteresis is defined as the difference between the opening and closing flow values of a contact. For example, the model PSR 11083 with minimal switching adjustment and increasing flow is switching on at 2.3 l/min and will switch off at
1.6 l/min at decreasing flow. Contact hysteresis = 0.7 l/min.
PSR/PSE
Contact protection
The reed contact may be damaged if the switch ratings are exceeded, especially while switching inductive or capacitive loads. This can cause unsafe conditions. By using a contact protection/isolation relay (e.g.: Model MSR 10), this problem can be overcome and the lifespan and switch rating of the reed contact can be extensively increased.
10. Maintenance
In cases the measured flow medium is not polluted, the PSR/PSE will remain virtually maintenance-free. Ferritic (iron) particles in the medium may deposit on the magnet, which can lead to problems. Bigger dirt particles can lead into blocking of the balance arm. To avoid those conditions, we recommend the installation of a magnet filter (e.g.: Magnet Filter model MFR). Depending on the amount of dirt present in the medium, we recommend the instrument to be checked and cleaned regularly.
Cleaning of the instrument
In hazardous areas the device requires regular maintenance and cleaning. The intervals are determined by the operator according to the environmental stresses on site. It should proceed as follows:
Shut-off the flow through the instrument. Ensure that there is no flow through the pipe and that the pipe is empty and
not under pressure.
Loosen the sleeve nut with a wrench (hex size 30) (only PSR-..). The upper switch housing and paddle arm can then be removed for cleaning. When cleaning the paddle arm, check that the flat spring is not damaged or
bent.
Prior to reinstallation, check that the o-ring is placed correctly in the lower
housing. Dirt particles on the o-ring will lead to sealing problems.
Insert the leaf-spring/paddle assembly into the lower housing and replace the
upper housing. Note that the suspension disk of this assembly must be correctly positioned within the recesses of the upper and lower housings.
Tighten the sleeve nut. Check that the upper half does not turn with the nut. Check seal tightness.
