Rising ball visual flow indicators provided by cenlub meet the needs of simple flow applications. These visual flow indicators [manufactured by flow-mon, uk] are best suited when calibrated flow indicators are not needed. Constructed materials includes high quality materials, these inline flow indicators have excellent chemical compatibility as well as are suitable for water, oil and gases for pipe size ranging from 8 mm to 40 mm. In case of no flow in the pipe, the white ptfe ball remains seated in the body socket. As the flow rises, the ball lifts out of the socket, clearly becoming visible. When there is flow in the pipes, the ball can be seen clearly, giving a positive confirmation of flow. Manufactured in stainless steel or bronze, the rising ball visual flow indicators can be used in plant protection applications to show lubrication or coolant flow to pumps, compressors or engines. Other of cooling water to specialised medical factory equipment, indicating chemical dosing on water treatment facilities, showing the presence of condensate in steam return lines, detecting changes in the condition and colour of liquids during processing, maintaining demineralised water rinsing essential to electronics components manufacturing.
