FLYGT a xylem brand Issued: 9/07 Supersedes: 6/07 Level Probe Typical Application t For use with Flygt pump controllers when combined with C MIO 201 (P/N 40-501404). The Level probe can also be used with conductance relays designed to operate with conductance probe. r 3 1/2" 1 Description The Flygt Level Probe provides a rugged, safe, reliable 2 and cost-effective means to measure liquid level for water ¢: 5" and waste water pumping applications.The Level Probe 3 ` may be ordered with one, three or ten electrodes with various spacing in between. The Level Probe is typically 4 connected to a pump controller (or conductance relay) that is designed to monitor a conductance probe and 5 perform level measurement. The level is detected when B the liquid level is high enough to touch one or more of 6 A the stainless steel electrodes on the Level Probe. The controller (or conductance relay) sends out a level sense signal to each electrode on the Level Probe. 7 The signal typically consists of a ±12V square wave, capable of supplying no more than 1.5mA. When the 8 —1 1/4" liquid being measured touches one of the electrodes, the square wave signal is diverted to ground through the 9 conductive liquid. The change in the signal is detected by the control device and used to determine the liquid __Tlevel. 10 2" SPECIFICATIONS ORDERING INFORMATION Electrode Material: Avesta 254 SMO High Grade Number Probe Electrode Cable Stainless Steel Alloy Part of Length Spacing Length Probe Casing Material: PVC Number Electrodes inches inches feet Cable: PVC/PVC A B C Multi-conductor 14-414000 1 7 X 50 Operating Temp: +32 to +140 °F 14-414001 3 19 6 50 14-414003 10 61 6 50 Both 14-414002 and 14-414005 10 97 10 50 14-414003 approved. 14-414006 10 115 12 50 Recommend 14-414002.
