We are considering using an automatic system to monitor and control additions of a saponifier to our Electrovert H400+ wash. Any recommendations on systems that other's have used? Any trade-offs on closed loop monitoring systems using pH versus refractometer? I thought that if you use water soluble masks that the dissolved materials might influence the dissolved solids measured with refractometer. However it seems that drag out with normal operation approaches 7 gal/8 hour shift. with a prewash and wash capacity of 95 gallons this means that over 12 shifts that the wash should be turned over but I suspect that all the material may not be turned over due to dead spots in the construction of the wash (i.e. 2" level in wash below a U joint that connects the prewash to the wash section). That said is location of the sensors critical- i.e. place them in these areas where the wash may be stagnant or items may settle to the bottom of tanks and heaters.
Thanks for the input
