Project Description

Vista Ball Flow Indicator

This sight flow indicator is ideal for you to visually check the flow, presence, colour and condition of a liquid, gas or condensate.

  • High quality robust design
  • Pressures up to 16 bar
  • Temperatures up to 200°C
  • Short lead times
  • Designed and manufactured in the UK

Application

The Vista ‘Ball’ is a single sided stainless steel indicator that can be used on pipe sizes from 8mm to 40mm (¼” to 1 ½”). 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.

Applications Include

  • Showing the presence of condensate in steam return lines
  • Indicating chemical dosing on water treatment plant
  • Ensuring that flow of cooling water is maintained to specialised equipment
  • Detecting changes in colour and condition of liquids during processing

Construction

The bodies are cast in high quality 316 stainless steel. The glass window is held in place by a stainless steel clamp ring and sealed with a Viton O’Ring, giving superior protection. The sight glasses can be supplied with screwed connections to NPT, BSP parallel or taper.

Quality

All Flowpoints indicators are manufactured to the highest standards.
The quality system is independently audited by BSI and certified to ISO 9001.
Full material traceability is maintained, material certificates and pressure test certificates are supplied on request.
