Yes, according to the wiring in the terminal block, the customer can choose whether the output will be active or passive. One of the common questions is "I didn't measure anything on the output" or "my pulse output is not working". Then you need to check the configuration (active/passive) to see what signal it is, the active one should be connected to an internal auxiliary source.
If the 4÷20 mA output shows a current of 1.5 mA - it means that there is no water in the pipe. So check the error condition on the display.
Yes, in an error condition the 4÷20mA current loop is reduced to approx. 1.5mA.
Yes, the meter is equipped with systems that are capable of detecting various faults. For example, when the cable is disconnected in the decoupled version, a problem with the power supply to the coils is detected and the electrodes break (error shown on the display). Similarly, the flowmeter autonomously verifies the functionality of the entire measuring system.
Yes, the meter is equipped with a flow simulation function, thanks to which the user can verify the settings of the outputs (pulse constant, pulse width, 4÷20mA limits) or the functionality and correctness of these outputs themselves.
You must check the minimum pulse width in the parent system and check the display reading ... over flow ... if this message appears reduce the pulse constant.
Check the flowmeter grounding itself to see if the piping is plastic, if so, use grounding rings. And carry out the earthing according to the instructions.
Maintain the required distance from pumps, bends, crosses and other sources of interference.
If diameter reduction is required, maintain a maximum angle of up to 7°.
If the sensor is mounted horizontally, make sure the "empty pipe test" electrode is on top.
Do not bundle the cable of the separated electronics with other cables. Interference may occur.
If the sensor is mounted in a metal pipe, the unit is grounded by the pipe.
If the sensor is mounted in a plastic tube, grounding rings are required
The earthing cable must be used according to the manual.
The power board is secured with 4 screws and connected with 3 plug-in connectors.
Passive
Requires external power supply
Commonly used in combination with a PLC
Active
Powered via the flowmeter's current source
To ensure that the evaluation unit housing is tight, it is essential to keep the gasket intact and clean (replace damaged gaskets immediately).
On cables leading to the electronic unit, create a "drip loop" downward so that water cannot run onto the connector or cable glands.
Repair the power leads (or outlets) in a similar manner and complete the installation by sealing the unit with a cover and tightening (be sure to lubricate the cover threads with silicone grease).
If the holes for the cable entries are not occupied, this must be done with a piece of cable or a plastic plug (to ensure tightness).
Proper installation (the flow sensor should be installed in any position in a vertical pipe).
The archive is available but can only be read via RS485 MODBUS protocol.
The archive consists of daily Vc, V+ register data
The capacity of the archive is 192 days, after which the oldest record is overwritten.
Closed approved FLOW 38 (MID) measuring devices according to MID directive, damage to them will result in loss of status!
If an error message is displayed, the product must be returned for service. (coil current, electrode break).When a warning sign is displayed, it is only an informative warning of a temporary meter condition between parameters (empty tube, pulse output, overflow pulse, imput saturation, AMP signal limit).
