Flow meters provide real-time insight into material delivery, helping contractors monitor performance, improve ratio accuracy, and reduce unnecessary material waste. The right data can make a measurable difference in application consistency and job profitability.

Consistent spray foam performance depends on maintaining the correct balance between the A-side (isocyanate) and B-side (resin) chemicals throughout the application process. When that balance changes, the result is spray foam off-ratio, which can reduce foam quality, waste material, and lead to costly callbacks. Off-ratio conditions often begin with small changes in processing conditions that go unnoticed until defects appear in the finished foam. Understanding what causes th
