BL 101 – Pool Line ORP Controller and Dosing Pump

Engineered to be an inexpensive solution for homeowner and maintenance companies to maintain the ideal ORP at all times of a swimming pool or hot tub. The BL101 Pool Line ORP 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 oxidizer (i.e. chlorine) to be dosed.

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

Πληροφορίες προϊόντος

BL101 ORP Controller and Dosing Pump is a system engineered for maintaining the ORP of swimming pools, hot tubs, and spas. Typically liquid chlorine is used as a disinfectant to keep the water safe from harmful bacteria. Chlorine, as an oxidizer, will increase the oxidation- reduction potential (ORP) of water when it is added to it. When the ORP value is greater than 650mV then bacteria that are present will be killed within seconds. The BL101 was developed to be an inexpensive solution for the consumer to maintain the ideal ORP value at all times. Simply insert the probe and injection valve in-line with the re-circulation pump and provide the chemical to be dosed.

Multi-color LCD

The BL101 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.

Intuitive LCD

Both ORP (mV) 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 ORP. 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.


On-Screen Features

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 .





Automatic Proportional Pump Control
The peristaltic dosing pump can be controlled by simple on/off or more advanced proportional control which helps prevents overshooting of the set point. When using proportional control the flow rate that is programmed, will be impacted by the proportional band used. The closer the reading is to the set point the longer it takes for the peristaltic pump to complete one revolution. If the reading is outside the proportional band then the amount of time it takes to complete one revolution is based on the flow rate programmed.




Oxidation Chemical Tank Level/Flow Switch Input
The BL101 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.

Built-in Dosing Pump

Peristaltic Dosing Pump

The BL101 features a peristaltic dosing pump that is superior to diaphragm versions due to the ability to self-prime when there is no liquid in the uptake line. The loss of prime can be problematic with a diaphragm pump due to the gassing of chlorine.

Brushless Motor

The brushless motor does not have any gears or brushes that can wear out. A brushless design provides for a long life and little maintenance. The compact stepper motor allows for very precision control over the dosing of the chemical.

Long-life Persitaltic Tubing

The industrial grade peristaltic tubing is chemical resistant and provides for a relatively long-life. As tubing stretches over time it can be easily replaced. No special tools required.


ORP electrode with flow cell

Three Configuration Options

The BL101 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 ORP/Temperature Probe

The BL101 uses the HI20083 amplified probe that incorporates both ORP and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector.

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. .
