The Products of John Moncrieff Glass Level and Flow Indicating

Flow Indicators

Flow Indicators provide a visual into pipelines or sealed vessels enabling the user to see immediately if flow is taking place and to observe colour, volume and condition of the flow.

Our range of Flow Indicators come with a choice of stainless steel, carbon steel and gun metal bodies, suit industrial applications with working temperatures up to 250ºC and working pressures up to 16 bar for the standard range and 40 bar for the high pressure range. We are also able to offer Flow Indicator units using more specialized materials such as duplex steel, aluminium bronze and quartz glass.

• Style P
  • This design has a plain spout cast in the body. It is used to check for the presence of a liquid where there is intermittent flow, partially filled lines or entrained air. It can be used in vertical or horizontal lines. The integral drip lip makes it ideal for leak detection.
• Style F
  • With the flap and easy to read scale the style F sight flow indicator is used to check the flow rate of a liquid in a pipeline. It can be used in vertical or horizontal lines and is ideal as a plant safety device where you need to maintain a constant flow, for example in lubricating or cooling systems.
• Style S
  • This model can be mounted in any pipeline position, and will operate over a wide flow range. With the highly visible PTFE spinner, the Style S is suitable for clear and cloudy liquids.
• Style T
  • The style T sight glass has a plain straight through borosilicate glass tube with stainless steel flanged ends and is used to check for the presence of a liquid where there is intermittent flow, partially filled lines or entrained air. It can be used in vertical or horizontal lines.
• Style W
  • This model is designed to provide a window for viewing the contents of a vessel or tank. Normally these are welded to the tank, but can be supplied suitable for bolting to a vessel or a pipe flange if required. The windows are either toughened soda lime or toughened borosilicate glass to suit the contents of the vessel.
• Vista Ball
  • The Vista ‘Ball’ is a single sided stainless steel indicator that can be used on pipe sizes from 8mm to 40mm (1?4” to 1 1?2”). The white PTFE ball rises when flow starts and is clearly visible from distances. The indicator must be installed horizontally with the glass dome positioned upwards.
• Vista Spinner
  • The Vista ‘Spinner’ is a single sided gunmetal indicator that can be used on pipe sizes from 8mm to 25mm (1?4” to 1”). The spinner starts to rotate when flow starts and is clearly visible from distances. The design offers low pressure losses and is suitable for installation in both horizontal and vertical pipework.

Level Gauges

John Moncrieff Ltd provides a range of liquid level measuring options. Simple oil level sights to measure tank level through to high pressure gauges designed for steam applications, all complemented by a full range of spares is also available.

All of these instruments are made to order and our engineers will provide expert guidance on the design and manufacture of the Magnetic Level Gauges for specific applications.
• Tubular Level Gauge
  • Tubular level gauges, are a cost-effective method of visual liquid level indication for tanks operating at low pressures. A basic standard oil tank level gauge consists of a toughened continuous section of borosilicate glass tube which is connected at both the top and bottom to an isolation valve.
  • The connection between the valve and glass is sealed by means of a rubber gasket contained within a union on the valve. The isolation valves used on this type of instrument are available either as screwed with union connection BSP or NPT, or they can be flanged to your request.
