PMV-1 ORP Controller Brochure
PMV-1 ORP Controller Manual |
The PMV-1 is an ORP controller designed for cooling tower or process application. It utilises a sensor to measure the level of oxidant in the water, when a certain level of ORP is reached the controller will trigger dosing cycles. The dosing cycle can operate in three ways. The first operates by cycling on / off timers, this is known as normal. The second operates in a proportional manner, dosing towards the set point at a reduced rate. This avoids over dosing. The third is known as adaptive proportional capacity to 'learn' from the behaviour of the system and adjust it's on and off by an algorithm programmed into the instrument. It also features an alarm and 4-20 mA output. |
