Water passing through the inline plastic housing spins a small vaned impeller mounted inside the flow tube, and the sealed sensor module clipped to the top of the body reads that rotation and converts it into an electrical signal carried by the three-wire lead set and keyed white plug, allowing the unit to connect directly to the existing boiler harness without splicing. Because the reading depends on water striking the impeller from the correct side, a flow direction arrow is molded into the side of the housing, making the required installation orientation clear when the sensor is fitted between the flanged pipe connections. It is supplied with the stainless steel retaining clips, O-rings, fiber washer, and mesh inlet strainer needed to complete a sealed replacement on compatible boiler models.\u003c\/div\u003e","brand":"Bosch Water Heater","offers":[{"title":"Default Title","offer_id":67602538299572,"sku":"kpi041-8-737-600-781-0","price":261.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/kpaulsupply.com\/products\/bosch-87376007810-flow-sensor","provider":"KPaul Industrial","version":"1.0","type":"link"}
