Description
Description
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 7.4, a form of chlorine, known as hypochlorite ion (OCl-), increases. This form of chlorine is 100 times 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 BL-100 was developed to be an inexpensive solution for the consumer to maintain the ideal pH level at all times.
Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed.
The BL-100 is available in multiple configurations including a meter and probe option, a kit for in-line mounting, and a complete package that includes bypass loop and panel mounted flow cell.
The kit for in-line and flow cell models includes aspiration tubing with filter and dispensing tubing with injection valve.
Peristaltic Dosing Pump
The BL-100 has a powerful built-in peristaltic chemical feed pump that utilizes a stepper motor which does not have any gears or brushes to wear out. This design provides for a long life and little maintenance.
Quick Connect Probe Input
The Quick Connect DIN connector creates a waterproof seal with the controller making it ideal for reducing electrical noise issues with the connection caused by humid environments.
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 prevent 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.
For example, a controller is programmed to have a set point of pH 7.40 with a 1.00 pH unit proportional band and the flow rate at 1.0 L/h. Any reading above pH 8.4 will cause the dosing of acid to be at 1 L/h. If the reading is at pH 7.90, which is 1/2 of the band, then the dosing pump will run at half speed or deliver 0.5 L/h of chemical. The closer the reading is to the set point the longer it takes for the pump to complete one rotation. This allows for very fine control of the pH value desired.
Acid Tank Level/Flow Switch Input
The BL-100 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.
Programmable Alarm System
Enables or disables 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.
Multi-coloured LCD Display
The BL-100 features a multi-coloured 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 light green; while in an alarm state the display flashes red.
About the HI-10053 Amplified pH/Temperature Probe
The BL-100 uses the HI-10053 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. The PVDF body of the probe has a 1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The probe body has a hex fitting for tightening snuggly with a wrench.
As an additional safety feature, the pH sensor is designed to have 0 mV value for pH 4 and not at pH 7 like typical pH electrodes. This is very important since a 0 mV potential will result when the internal glass is cracked and shorts with the reference cell.
For the HI-10053 the 0 mV value will be pH 4 and this type of reading will produce an alarm state (when programmed) and disable the pump from dosing. A standard pH electrode would have a pH value close to 7 and could result in either no dosing or excessive dosing based on the actual value and programmed set point.
