We offer a variety of products, from PVC molded, to panel mount flow meters with an adjustable flow rate valve that allows you to limit your maximum flow rate by simply adjusting the valve. These flowmeters comprise a vertically tapered tube through which the fluid to be measured is passed, from the smaller end up to the larger. As the fluid flows through the tube, it forces an indicator (float) upward. The clearance space (area) between the float and tube increases as the float approaches the top of the meter. This increasing area requires a larger amount of fluid to force the float higher. By varying the taper of the tube, the mass of the float, and the length of the tube, different flow ranges can be calibrated.
NOTE: Flow rate can be read by matching the increments on the tube with the edge of the float:
