Max Machinery Inc. has announced the successful application of its Model 234 Positive Displacement Flow Meter in metering antiscalant liquids in the Reverse Osmosis (RO) water desalinization process. With the RO membranes making up as much as 40% of the RO plant's original construction cost, their proper maintenance is a primary concern. Through the use of small doses of antiscalant chemicals, mineral scale formation is inhibited in the process and on the membranes. Monitoring of this additive is crucial, as inadequate dosing can cause the fine membranes to become irreparably clogged in as little as 48 hours. The Model 234 piston-type positive displacement flow meter offers a drift-free K-factor, high repeatability (0.1%) and direct measurement of the antiscalant liquids flow. No longer is the user dependent on indirect measures of flow such as pump speed or stroke count. The meter is rugged, dependable and not affected by changes in fluid viscosity or flow profile. Even pulsating flow streams can be accurately measured.
