Adjustable Dosing Relay – The BL-932700 features a dosing relay which may be configured to dose above or below a user programmable mV setpoint.

Selectable Overdose Protection – The mini controller may be programmed to deactivate a valve, pump, or connected device if its activation continues over a selected time; adjustable from 5 to 30 minutes.

Selectable Control Override – With the flick of a switch, normal “Auto” operation may be overridden turning your connected device “Off” from operation or always “On.”

Analogue Output Communication – The BL-932700 features a 4 – 20 mA analogue output for connection to a data logger, chart recorder, or other device.

External Disabling Feature – A normally open contact may connect to a level controller or flow monitor. This safety feature may be used to prevent continuous dosing in the event of specific or undesired system conditions.

Matching Pin Connection – An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
