The FHKSC Flowmeter is a general-purpose de-vice that has been specially designed for coffee machines that use vibratory pumps. The device is installed between the water container and the vibratory pump (on the suction side) and in this way prevents the measuring errors that arise during pulsating water flow caused by vibratory pumps.
Specific applications: Thanks to its closure system, the water outlet side can be assembled in four different positions. Centrally ball catch fitting (Ø 3.9mm) on the lower part of the flowmeter. Doubled isolation (water/electronics) according to the standard IEC/EN 60335-1: 2001/2002 + A1: 04+A2: 06+A11: 04+A12: 06.
*
Special regulations which must be complied with by the flowmeter manufacturer apply to each coun-try, e.g. CE, NSF, FDA and SK. The various media flowing through the flowmeter differ from applica-tion to application. You are advised to enquire with the medium manufacturer as to whether the entire installation and the flowmeter are resistant to the medium itself (see Material)!
RESISTANCEDIGMESA electronic circuitry is always designed for operation with DIGMESA flowmeters. Please note the following if connecting to other elec-tronic circuitry:
•The flowmeter does not supply an output voltage but switches the signal terminal to 0 V ground (actuated) or leaves it open (non-actu-ated)
•There must be a pull-up resistor between power supply + and signal depending on elec-tronic circuitry!

The values specified must be considered as approximate values.
The number of pulses per litre may differ depending on medium and installation.
We recommend to calibrate the number of pulses per litre in line with the complete installation.
• Ensure that there is no fast-pulsatory movement of the media
• Ensure that there are no reverse pressure surges
• Ensure that there is no air in the system
• Keep the pressure loss as small as possible
• Note the mounting position of the flowmeter
• Min/max flow should be in the linear range of the selected flowmeter
• Clean the system at appropriate intervals
• Avoid electrical current peaks
• Incorrect cabling of power supply +, signal and ground will destroy the flowmeter
• Do not mechanically load electrical contacts
• Avoid moisture on the electrical contacts
• Avoid stray pick-up via the cable (Do not lay cables in parallel with high current loads)

The values specified must be considered as approximate values.
The number of pulses per litre may differ depending on medium and installation.
We recommend to calibrate the number of pulses per litre in line with the complete installation.
• Ensure that there is no fast-pulsatory movement of the media
• Ensure that there are no reverse pressure surges
• Ensure that there is no air in the system
• Keep the pressure loss as small as possible
• Note the mounting position of the flowmeter
• Min/max flow should be in the linear range of the selected flowmeter
• Clean the system at appropriate intervals
• Avoid electrical current peaks
• Incorrect cabling of power supply +, signal and ground will destroy the flowmeter
• Do not mechanically load electrical contacts
• Avoid moisture on the electrical contacts
• Avoid stray pick-up via the cable (Do not lay cables in parallel with high current loads)
