The R O T A M E T E R — its basic advantages over head-type meters
WIDE FLOW RANGE20-to-1 easily obtained
Î
The wide flow range of the rotameter will help, you greatly to obtain flexible flow rate control. Changes in product demand, shifts from one product derivative to another, seasonal load variations, conversion t o an entirely different product—all of these possibilities happen and often require a lower or higher flow rate than you originally planned. Under these circumstances, your choice of the Fischer & Porter rotameter with flow ranges as great a s 20 or 3 0 to one from maximum to minimum flow will save in the number of meters required and will enable you to shift smoothly to new operating conditions without a moment's delay. The wide flow range of the Fischer & Porter rotameter is only one of many advantages which are thoroughly described in our latest 28-page booklet entitled "A New Era in Flow Rate Measurement," just off the press. It contai authoritative information and an interesting pictorial pre «tation of the subject that is highly instructive. We will be glad to send you a copy without obligation.
