Variable-area flow meter GU

volumefor liquidsvertical

Gapmeters type GU are glass tube Variable Area Flowmeters for direct display of liquid or gas flowrate. The GU housing provides a robust rigid frame, suitable for mounting directly into plant pipework, protecting the glass tube from pipework stress and random plant damage. The safety Perspex window gives good flow visibility, whilst protecting the operator. A safety blowout disc on the rear of the housing provides a relief vent for process fluids, in case of glass tube damage. Glass tube VA flowmeters are simple and reliable in operation, and instantaneous in response – they offer flow visualisation to the operator, and the float rotation gives confirmation of correct meter performance. Standard tubes and floats offer low line pressure loss and a high resolution 100mm linear scale, fused into the glass tube. Fluid flow vertically upward through the tapered glass tube causes the float to rise to an equilibrium position. Flow rate is measured on the scale of the flow tube, along the top edge of the float. The borosilicate glass tubes are individually scaled according to customers requirements, and individually flow calibrated.
