By-pass mountings are particularly useful in applications involving oily coatings, low suspended solids, or moderately viscous materials. The flow cell is easily isolated using inexpensive block valves, to service the electrode without the need for any tools.

An inexpensive flow cell accelerates the velocity past the electrode in a predictable manner. The 3/4" flow cell's restricted 1/4" diameter orifice provides a 2 ft/sec velocity per GPM past the electrode's flat sensing surface. Flow rates of 1 to 5 GPM provide excellent cleaning velocities in low viscosity applications. Exact control of flow rates is not required.

Lower flow rates are used when viscosities are higher. Even 1 GPM still provides excellent flow in shear to assure that fresh material is always at the measuring surface.

In the food or dairy industry, only a tiny rate of fluid  product needs to be pumped through the flow cell. This material can then be directed to waste disposal, with no chance of glass contaminating the consumers product.   Rates of 0.5 or even 0.2 gpm will provide accurate measurement of pH. The pH glass sensing technology is acknowledged to be the easiest to use, more repeatable, more accurate, more dependable and lower cost than solid state sensing technologies.
