BL100 PooLine pH Controller & Dosing Pump

Engineered to be an inexpensive solution for homeowner and maintenance companies to maintain the ideal pH at all times of a swimming pool or hot tub. The BL100 Pool Line pH Controller and Dosing Pump is a complete solution with both a process controller and a chemical dosing pump. Simply insert the probe and injection valve in-line with the re-circulation pump and supply the acid to be dosed.

  • All in one solution for maintaining the proper pH
  • Industrial process probe with 1/2″ NPT threads for insertion into re-circulation line
  • Input for level controller or flow switch

BL100 pH Controller and Dosing Pump is a system engineered for maintaining the pH of swimming pools, hot tubs, and spas. Typically chlorine, whether liquid or solid, is alkaline and will raise the pH of the water that it is added to. As the pH increases above pH 7.4, a form of chlorine known as hypochlorite ion (OCl) increases. This form of chlorine is 100 time less effective at killing bacteria as compared to the other form of chlorine known as hypochlorous acid (HOCl). For this reason it is important to maintain the correct pH level in order to ensure that the more powerful hypochlorous acid form is available for disinfection. The BL100 was developed to be an inexpensive solution for the consumer to maintain the ideal pH at all times. Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed.

Multi-color LCD

The BL100 features a multi-colored LCD that provides for a quick way to see the status of the pool controller. If in control mode and operating as intended the display will be green. If control is not enabled then the display will be yellow while in an alarm state the display flashes red.BL100 DISPL

Intuitive LCD

Both pH and temperature are displayed with status icons that show when the pump is dosing and the control mode status.

Programmable Alarm System

Hanna controllers allow users to enable or disable the low and high level alarms for pH. When an alarm is activated, all dosing will stop. For added safety, the alarm system also offers overdosing protection in that if the set point value is not corrected within a programmed time interval then the meter will go into alarm status.

Acid Tank Level/Flow Switch Input
The BL100 allows for a connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off.

BL100 LEVEL

Adjustable Flow Rate
The flow rate from the dosing pumps is adjustable from 0.5 to 3.5L/h. Larger bodies of water require more chemical to be dosed than smaller ones in per unit of time. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point .

BL100 FLOW

pH electrode with flow cell

Three Configuration Options

The BL100 is available in multiple configurations including a meter only, meter and probe, and
 a complete package that includes bypass loop
 and panel mounted flow through cell. All models include aspiration tubing with filter and dispensing tubing with injection valve.

HI10053 Amplified pH/Temperature ProbeBL100 ELECTRODE

The BL100 uses the HI10053 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector. The built in amplifier helps to reduce electrical noise from recirculation pumps to provide for a stable, reliable measurement. The pH glass used is ideal for low conductivity water and provides for fast response..

NPT Threads for In-line and Tank Mounting

The ABS body of the probe has a 1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The back end part of the probe has 3/4” NPT threads for submersion/ tank mounting. The probe body has a hex fitting for tightening snuggly with a wrench.
