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 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.

Flow sensor is a device used for sensing the rate of fluid flow. It is a sensing element used in a flow meter, or flow logger, to record the flow of fluids. There are various kinds of flow meters, including some that have a vane that is pushed by the fluid, and can drive a rotary potentiometer, or similar device. These are related to devices called velocimeters that measure velocity of fluids flowing through them. Laser-based interferometry is often used for air flow measurement, but for liquids, it is often easier to measure the flow.

Flow Straighteners are designed to avoid any effect that flow disturbances generate on metering. Flow straighteners are available to eliminate vortexing of product when there is a short distance of straight pipe before and after the meter. The flow straightner lengths are 2″ x 24″, 3″ x 36″ and 4″ x 48″.

Dry material flow switch is used to detect the flow of dust through a filter in a dust collector or bag house. It can also be used as a flow/no-flow switch for powders or granulars in chutes or pneumatic conveying lines. It comes complete with the electronic circuit board mounted in an enclosure, low noise coaxial cable and connectors, and a stainless steel probe mounted in an explosion-proof enclosure.

Flow Switches are sensors that generally insert into the pipe or duct in which flow is measured. It indicates the presence of flow actuating the contacts when a certain flow rate is reached. They are based on the use of a reed switch. These devices passes signal when the water in a system is flowing. It prevents systems from bleeding and feeding chemicals when the cooling tower is not operating.

Flow Switches indicate the presence of flow, actuating the contacts when a certain flow rate is reached. It is based on the use of a reed switch. The fluid flow displaces the magnet, which then closes the reed contacts. These are sensors that generally insert into the pipe or duct in which flow is measured.

Flow/No-Flow Switch monitors turbine, gear, paper-machine, hydraulic & cutting oils as well as water with standard 1/2-, 3/4-, 1-, 1 1/2-, & 2-in. NPT-size connections. This switch enables automatic activation of a designated remote event, which includes an alarm light or system/oil pump. The switch handles pressures of up to 125 psig and liquid temperatures up to 200°F.

Flowmeters can measure rate of flow or quantity of a moving fluid in an open or closed conduit. They are available in a variety of flow rate range. The height of the float in the flowmeter indicates flow rate. It consists of both primar and a secondary device.

Fluid Filled Gauges are meant for pulsating loads such as with hydraulic systems. Fluid-filled gauges contain expensive safety valves for relieving excess pressure or employ some type of temperature compensation means to avoid erroneous instrument reading.

Fluid metering system includes a housing having a piston chamber with first and second spaced ends and at least one housing inlet and outlet passage. The housing inlet and outlet passages communicate with the piston chamber. A piston is disposed in the piston chamber for reciprocal movement between the first and second ends of the piston chamber to alternatingly define first and second volume. At least one first slot, and second slot are formed on the outer surface of the piston, and extend from respective ends of the piston toward the respectively opposite ends. The piston is rotatable within the piston chamber to alternatingly bring one of the first or second slots in registration with the housing inlet passage, while simultaneously bringing the other of the first or second slots in registration with the housing outlet passage.
