Glass Variable Flow Meters – LGX Series

The LG series are our low cost miniature Glass Tube VA flowmeters for surface panel mounting where small size is important. The RGTF glass flow tubes have 30mm scale length and have standard scales for air.

Easy to use, high visibility scale. Simple and reliable. Gas flow measurement. Operator confidence from float rotation. Instantaneous response. Accuracy up to ±1.25% FSD. Air flow range 5 cm3/min to 150 L/min. Linear scales, typically 10:1 range. Glass tube removal without tools. Option of single or dual alarms. Option of integral needle valve. Special scales available on request. Models available for Air, Gas and Water Measurement.

Glass Variable Flow Meters – NGX Series

The NG series are our low cost frames for the standard 100mm scale glass tubes. Ideal for panel mounting, the NG series are supplied with mounting studs and a rear facing exhaust vent to safely exhaust process fluid should a tube fail. Models can have rear facing or in-line process connections and the NGV units have a built in needle valve for flow control. Float and scale visibility is improved through the use of a clear polycarbonate cover set against a white background.

Robust construction. Safety housed for operator protection. Easy to use, high visibility scale. Simple and reliable. Gas flow measurement. Operator confidence from float rotation. Instantaneous response. Accuracy up to ±1.25% FSD. Air flow range 5 cm3/min to 150 L/min. Linear scales, typically 10:1 range. Site interchangeable tubes. Option of single or dual alarms. Special scales available on request. Models available for Air, Gas and Water Measurement.

Glass Variable Flow Meters – GU Series

The GU series Glass VA flowmeters safety housed construction provides a rigid protective structure around the flow tube, to allow installation in unsupported pipework or to provide extra protection to operators on high pressure or corrosive applications. The tube and float is viewed through a solid Perspex window.

Instantaneous response. Reliable operation. High visibility scale fused into flow tube surface. Float rotation gives operator confidence of correct performance. Borosilicate glass tube, anti-static coated to prevent problems. Flow ranges from 10:1 to 150:1 available. Individual flow calibration. Standard gases – Air, Oxygen, Nitrous Oxide. Customised logo available. Anesthetic tubes are made to order.

Glass Variable Flow Meters – Platon Glass VA Tube

The Platon Glass VA Flowmeter Tubes are widely supplied for use on medical equipment such as Anaesthetic trolleys. Available in keyed lengths and colour coded to avoid incorrect installation, standard tubes are calibrated for oxygen, nitrous oxide or air.

Please contact us specifying the gas, flow range, accuracy and tube length required for a specific product and price quotation.

The Platon range of Borosilicate Glass flowmeters are based on the well known Variable Area principle of flow measurement. Using various combinations of tubes and floats, thirteen standard gas, and seven liquid sizes are available with scales to suit the application. All tubes are flow tested prior to scale placement, which is fused into the glass to provide clear and long lasting visibility. The fluted floats rotate to indicate free movement and therefore reliable operation. Available separately or complete with a flowmeter frame to suit your application. Use the tables to choose a standard tube or consult our Sales Team who can help with a custom scale.

Glass tube Variable Area 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 flowing vertically upwards 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. Platon borosilicate glass flow tubes from RM&C are individually scaled and individually flow calibrated according to customers requirements. Custom scales are produced using our “Reynolds Curve” prediction software, which corrects for the effects of changes in density, temperature, pressure and viscosity of the working fluid.

Anesthetic tubes are made to order. Please contact us specifying the gas, flow range, accuracy and tube length required for a specific product and price quotation.
