1 23 Years in the Industry Over 1000 End-Users Specify MultiTrode

2 Specialists in level sensing and control for pump stations USA, UK and Australia 23 years in this market Corporate offices –Boca Raton, FL –Bristol, UK –Brisbane, Australia Supply products to 15 countries through our own sales team or value-added reps & distributors MultiTrode - Company

3 Conductive Level Probes Reduces maintenance costs No more false readings or burnt-out pumps Simple to install and guaranteed for 10 years Cuts the risk of spills Two Basic Types Multiple measurement points for primary level control –10-sensor probe most common Single point for back-up control

4 The Probe – how does it work? No electronics or moving parts in the wetwell The control or monitoring device in the wetwell: applies 10v a.c. to each sensor looks for current flowing to ground With 10 sensors we get 10% resolution of level Works in spite of fats, oils and grease (FOG)

5 Fat and Grease This probe was installed in a wastewater pit 10 years ago, without being cleaned. The probe still works reliably today. Over 100,000 pump stations installed with probes.

6 Examples Extreme FoamHeavy SludgeFat and Grease

7 MultiTrode Probe - Installation Mount near the inflow (turbulence keeps it cleaner) Install bottom of probe a little above the snore point of the pump Ensure 12 inches of clearance around the probe

8 MultiTrode Probe - Installation Single sensor example - for single pump start/stop application Mounting bracket not included with single sensor probes The extended bracket is shown here

9 Probe comparisons Compared with other level devices, the probe is simpler and more reliable –Ultrasonics are complex and hard to troubleshoot –Pressure transducers fail and need cleaning –Ball floats need constant cleaning –Bubblers have mechanical parts

10 Floats / transducer replacement MTIC –Works with a 10-sensor probe –10 relay outputs (corresponding to level) –4-20mA output (stepped) –Level indication How is control done? –MTIC connects into the existing control system –Can be used for simple control but has no pump logic, no alternation, etc

11 Duplex pump control MTDPC –Works with a 10-sensor probe –Operator interace with level indication, manual/off/auto control, pump fault and level alarm reset –Alternation or fixed lead/lag –Setpoint adjustment via keypad How is control done? –MTDPC is the control system –Replaces relay logic or PLC –Replaces switches, lights, push buttons

12 Single pump control MTR and MTRA –MTR works with 2 single-sensor probes –MTRA works with 2 or 3 single sensor probes –Simple but effective & economic and always ultra-reliable How is control done? –ON/OFF from the 2 sensors –With MTRA, alarm from a 3 rd sensor, or level stays above ON sensor –MTR can do pump up or pump down –MTRA is pump down only

13 Level alarm relay SafeSmart, Safe-FS –Works with failsafe single-sensor probe –Two Relay outputs – level alarm and probe fail How does the failsafe probe work? –Two wires connected to the same sensor –Checks for continuity every 10 seconds

14 SafeSmart Backup controller Safe-TL & Safe-FSP –Works with failsafe 3-sensor probe (ON, OFF, ALARM) –Provides a backup control system for 1 pump in any wastewater pump station –Or primary single pump control How does the unit work? –Level from backup probe –Manual/hand input –Wont run pump if its too hot

15 Comparison - SafeSmart controllers & MTR SAFE- TL SAFE- FSP MTR A Comments One pump control + alarmXXX Thermal fault input inhibits pump (including thermal FLS from Flygt pumps) XXStops pump running when too hot Seal fault input inhibits pump XPotential miniCAS replacement Manual (hand) inputXXAllows over-ride which can be inhibited on pump thermal fault Keypad for inner doorX Works with failsafe probe input XXLED indication for loss of probe Relay output when loss of probe XControl or telemetry system can discriminate between high level and loss of probe

16 Conclusion The MultiTrode probe is the best solution for wastewater level measurement –Simple, reliable and low maintenance MTIC – float or transducer replacement MTDPC – duplex pump controller MTR / MTRA – single pump control Safe-FS – failsafe high level alarm Safe-FSP & Safe-TL – backup pump controller (single pump)
