Abstract: A flow meter having a magnetic base sensor for electrical feedback of flow rate is disclosed. A float rod carrying an indicator and a magnet moves within the flow meter body with and the flow being visually read and electronically read.
Abstract: An apparatus is provided for separating nitrogen gas from methanol liquid in a furnace hardening system. The furnace is housed in a building and connected by a piping system to a methanol storage tank located outside the building. The tank is capped with nitrogen to pressurize the system at high pressure and a pressure regulator reduces the pressure at the furnace. A flowmeter unit controls the flow rate. The gas separating apparatus includes a vessel having a liquid inlet and a liquid outlet in the lower end. The methanol containing nitrogen is introduced under pressure into the inlet and is discharged from the outlet at a lesser flow rate to provide an accumulation of the liquid in the vessel, while the nitrogen gas is released from the liquid and collects in the headspace of the vessel. A float is disposed in the vessel and floats on the accumulated liquid in the lower end of the vessel.
Abstract: A protective shield for the sight glass of a flow meter. The flow meter includes an elongated guard having a slot that houses a sight glass, and a flow indicator carried by a float moves vertically within the sight glass and the fluid flow is read on a scale mounted on the guard and bordering the slot. A transparent open-ended protective sleeve is disposed around the guard and is retained on the guard by a spring clip that extends inwardly of the sleeve and engages an abutment on the outer surface of the guard.
Abstract: An improved apparatus for separating liquids and particularly separating oil from the surface of water contained in a tank. The apparatus includes a partially submerged drum mounted to rotate in the water tank and a film of oil and water is picked up on the surface of the rotating drum and removed by a doctor blade. The removed oil and water mixture flows through a trough and is discharged into the upper end portion of a vertical tube. The lower open end of the tube is located beneath the level of the water and the tube has an overflow outlet located at a higher level than the level of the water. The oil, having a lesser density than the water, will collect in the upper end in the tube and the level of oil will rise and is discharged through the overflow outlet, thereby providing a full separation of the oil from the water.
