Sensors & Switches – Liquid Flow Devices
Liquid flow devices include instantaneous flow sensors, mechanical flow switches giving an ouput signal at a set point, and a flow controller for supply stability. Sensors within the collection are optimized for a variety of conditions, including compatibility with water, coolant, or chemicals; detection method; space constraints; and manifold configuration. Outputs range from simle ON/OFF confirmation signals, mA or V analog, or digital IO-Link. Review the categories to select a product best suited for your application.
Flow sensors provide instantaneous flow readings. Sensors can be discrete or configured into a manifold, with integrated displays or remote and paired with a monitor display to mount in the panel.
IFW is a mechanical switch for the detection and confirmation of liquid flow. The flow body houses a diaphragm responsive to flow rate. A connected rod and lever mechanism triggers a micro switch at a manually adjustable set point. An optiional light, either neon (VAC) or LED (VDC), can indicate operation. Compatible liquids must be non-corrosive to the brass and copper alloy wetted parts and NBR or optional FKM diaphram. Wiring method can be normally open or closed with a range of voltages. A terminal box and CE compliance are also optional.
IF3 is a mechanical switch for the detection and confirmation of liquid flow. The device threads into a flow path, where the liquid pushes against the paddle. This actuation triggers a micro switch at a manually adjustable set point. Short, medium and long paddles are provided with each model. Paddle size to install will be determined by the pipe size and flow rate. Options include IP42 or IP44 rated enclosures, and either brass / bronze or 304 stainless steel wetted parts. Compatible fluids must be non-corrosive to these materials. Wiring method can be normally open or closed with a range of voltages. CE compliance is also optional.
Flow Controller for Water
FC2W is a flow controller for water between 0-50°C. A motor driven adjustable flow restriction works together with feedback from a Karman vortex flow sensor to respond to an analog input signal establishing the flow rate. When a single water supply source is divided into multiple lines, the flow rate between lines can be inconsistent. FC2W controllers can adjust flow on each line to a constant rate. FC2W does not include a flow shutoff feature. Pair the controller with a VXZ 2-port soleoid valve to stop flow for any reason. The device includes an error status LED. This is a grease-free product.
