Flow data sensor ZE 3000
micro-processor controlled for accurate flow
measurement and evaluation
330501 - 05/06
Product description
The ZE3000 emits a 4..20 mA signal according to
industrial standards, generated in the DS15 by the
precise magnet angle detection of the magnetic
float.
Existing flowmeters (with magnetic floats) can be
easily retrofitted with the ZE3000 to electrically
signal the flow and, for instance, to further process
the values in a PLC for process control or to directly
display the flow rate.
This micro-processor controlled unit is programmed
for the DS15 concerned! This guarantees accurate
flow measurement and evaluation.
IMPORTANT: The DS15 to which the ZE3000 is to be
fitted must be known in advance!
Features:
• 2-wire technology
• 4..20mA analog output
• 8..28VDC input
• Individual programming adapted to the DFM
• 11 point calibration
• non-volatile value storage
• 0 button to compensate for the surrounding
magnetic influences
• Factory setting of the lower limit value (low-cutoff)
0..99% according to customer’s specifications
• Factory settable time lag (low-pass-filter)
0.1...2.5 sec according to customer’s specifications
• Measuring accuracy better than 0.5%
Pin 1: 8..28VDC
Pin 2: GND
Installation
Screw clamps are used to fit the ZE3000 on the
dovetail guide of the flowmeter. The plug connector
is located in the upper section.
During installation, ensure that the notch of the
ZE3000 coincides with the 50% mark on the DFM
scale.
Following this, proceed with the wiring according to
the plug assignment plan.
Plug assignment
Start-up
Once installed and the voltage is applied, press the
0 button for at least 2 sec to compensate for
surrounding magnetic influences.
During this phase ensure that the float is in its
bottom position, i.e. no flow must take place!
