4. Regulation Use The KOBOLD KAL-A.. Flow Meter is intended for use in measuring moderate flow rates of low-viscous or dirty liquids. The KOBOLD KAL-AK.. Flow Meter is intended for use in measuring and monitoring moderate flow rates of low-viscous or dirty liquids. -
Page 4: Operating Principle
Attention! The flow ranges specified in the table above have been calculated for each pipe diameter based on the known velocity range of the KAL-A(K). It must be noted that flow in pipes is non- uniform across the pipe cross section, and approaches zero at the pipe wall. -

Prior to installation Ensure that the actual system flow rate the is within the measuring range of the KAL-A(K). Ensure that the maximum system temperature and pressure are within the limits specified per section (see section 12. Technical Information) - Page 6 If the flow rate has reached the set point value selected by the user, then the LED is flashing. Bi-coloured LED (KAL-A) If bi-coloured LED is green: Instrument is in operation mode. If bi-coloured LED is flashing green: Instrument is in calibration mode.

Page 8: Output
The reference point for the NPN-output is +24 VDC PNP-output The semiconductor output switches to +24 VDC or is highly resistant. The maximum output current is 400 mA. The reference point for the PNP-output is GND (GROUND = 0 VDC). Page 8 KAL-A(K) K05/1116... -

When the bi-coloured LED stops flashing, the zero flow calibration is set. The device now switches automatically to the monitoring mode and displays no flow. The LED strip is not illuminated; only the threshold value LED is flashing. KAL-A(K) K05/1116 Page 9... - Page 10 The adjustment procedure is now complete. It may be repeated as often as necessary. c) Measuring mode After adjustment, the flow monitor is once again in measuring mode. The flow is constantly monitored and the actual value of the flow speed is displayed on the LED strip. Page 10 KAL-A(K) K05/1116...

(calcination etc.) and if necessary be cleaned. 11. Diagnostics The KAL-A(K) continuously self monitors the sensing probe and the micro- processor system upon short-circuit and circuit breaking. Any fault in these parts of the electronics will be signalled by a flashing red bi-coloured LED and a simultaneous flashing LED-bar ( ... -
