Flow Recorders is installed to know the quantity of sewage which is pumped per unit time, may be in the form of rectangular weir, standing wave flume and triangular weir or venture meter. Flow recorders accomplish their mission without interrupting the accurate registration of the water meter and, typically, without altering the existing meter configuration. Flow recorders using magnetic pick-ups sense the magnetic field generated by the magnetic coupling of a water meter's internal drive magnets and convert the magnetic flux change into a digital pulse that is logged into memory and later downloaded into a PC for analysis. It can identify the percentage of flow in low, medium, and high flow ranges.

Flow Regulator Plates are used to control the flow of water. It can be installed in conduit or channel. The operation of the regulator, depending on the upstream head and discharge, switches between orifice flow.

Flow regulators provide a unique, leak-free, single-point manual flow control. This regulator incorporates the proven mechanical flowmeter and integral needle valve in a compact design. Very few moving parts improve reliability and leak-free operation. Used singly or in combination with a water manifold, the flow regulator allows manual control of individual cooling water lines.
