OVERVIEW:

The CTS from Fluid Metering Inc. is the solution for

accurate, maintenance-free injection of liquid sodium

hydroxide (Caustic Soda) typically used for pH

adjustment, as well as other chemicals used in water

and wastewater treatment applications.

The CTS system eliminates check valves and/or

peristaltic tubing typically present in traditional

chemical metering systems, which are the primary

sources of routine maintenance and downtime. The

CTS does not lose prime, even against pressure, or air

lock. The CTS is available as a complete system

(CT1V & CT2V) consisting of the CTS Pump Module

and C100A Variable Speed Controller, or can be

supplied alone to be used with a compatible controller.

The CTS Pump Module is a unique valveless pump

design consisting of a rotating and reciprocating

(CeramPump®) ceramic piston, direct coupled to a

variable speed drive motor. The CTS pump injects the

caustic soda directly into the main water stream, at

back pressures up to 125 psi.

The C100A Variable Speed Controller from Fluid

Metering, Inc. provides an ideal control interface for

the CTS. The C100A supplies a variable 0-90VDC

power source which can be controlled either manually

using a from panel mounted rotary dial, or

electronically via a 4-20 mA control input.

SPECIFICATIONS CTS Chemical Treatment System Supply Voltage: 0-90 VDC** CTS Supply: 1/4” FNPT CTS Outlet: 1/4” FNPT INSTALLATION & SETUP CTS MOUNTING (See diagram page 3) IMPORTANT NOTE: Supply and Outlet fittings contain Buna-N material which is not compatible with fluids containing chlorine. Do not use the CTS with hypochlorite, chloramine, or any fluids which contain chlorine compounds in ANY concentration. Output Volume: 6.5 GPH max. - CT1(V) 15 GPH max.- CT2(V) Output Pressure: 125 psi max.

FLUIDIC CONNECTIONS Installation Notes: The CTS has two 1/4” FNPT fluid connections. The INLET (Supply) connection is a 1/4” FNPT fitting located on the lower right side of the enclosure and connects the CTS with the chemical supply reservoir (carboy, tank, etc.) Inlet tubing is customer supplied and should be semi-rigid and sized adequately to accommodate the required flow rate to prevent cavitation. Minimum recommended inlet tubing diameter is 1/2” I.D.

Calibration Reference Charts Maintenance Periodic: Rinse the piston where it enters the seal using the small squirt bottle provided. Simply use water. This will help to eliminate any build up of crystals that may damage seals. Perform this procedure once a day, week, or whenever you are in the pump house. Check for leaks, drips, .. etc. Wipe clean as necessary. Scheduled: 4 months or 1000 hrs. Check for leaks at all fittings and pump head. Change seals and/or fittings if necessary.

C100A Variable Speed DC Controller GENERAL The FMI C100A Variable Speed DC Controller is designed to operate with FMI Variable Speed CL and CTS Drives. The C100A features both manual speed adjustment (“ON” position) using a front panel mounted rotary control, as well as electronic speed control (“AUTO” position) via a 4-20mA signal from an external source (sensor, analyzer, process controller.. etc).

WIRING PROCEDURE 1) Remove the four (4) cover screws to remove the cover and gain access to the terminal strip. Note: When removing the cover, take care not to damage the cover gasket or the wires connecting the cover controls with the main circuit board. 2) If an external 4-20 mA control source is used, (typically a sensor, analyzer, or PLC etc.), connect the 4-20 mA output of this device to the +1 and -2 terminals as shown below. 3) After all wiring is complete, replace the cover.

Tips from the Field The CTS has been dynamically tested, including the integrity of all internal fluid connections, prior to shipment. The C100A control unit is factory adjusted for optimum performance with the CTS, and no additional adjustment of internal trim pots should be required. However, if a newly installed CTS with C100A System fails to operate properly, the following is a step by step troubleshooting guide to determine the cause and corrective action.
