Flow Meter – Sika Variable Area Flow Meters

T&D, the specialist supplier of Metering products for water, gas, heat and energy applications are distributors for the Sika range of flow meters.

Sika oval gear flow meters are also available

Flow Meters

Variable Area Type

Sika variable area flow meters are used for monitoring flow rates in application areas such as:

  • Water treatment
  • Monitoring cooling circuits

Sika variable area flow meters are used in pipelines and determine the volume flow of liquids or gases  – the flow meter consists of a conical measuring tube with a float inside it.

The measuring principle is based on the body being vertically deflected through the flowing medium. Various forces act on the float – the flow resistance, the buoyant force and the weight force of the body.Basically, if the volume flow rises, the float is lifted.

The current flow is indicated on the scale at the top of the float.

SIKA VS flow meters

VS flow meters feature a water scale in l/h and a % scale as standard. Optional air scales are also available for various operating pressures. Two adjustable reference value indicators facilitate monitoring of the rate of flow. Limit contacts are available as accessories.

limit switches

Limit Switches

Limit Switches

Sika limit switches VSK1 and VSK2 serve for external monitoring of limited flow rates on variable area flow meters – installed on the check rail of the flow meter and adjustable to any switching point on the respective scale.

Function
The magnet in the float closes or opens a reed contact encapsulated in the limit switch : the switching function is bistable ensuring the switching state is maintained when the magnetic float is at a distance from the contact. Important to note when retrofitting limit switches is that the standard float must be replaced with a magnetic float.

SIKA FLOW SWITCHES – WRAS appRoved

Flow switches utilising switchless design for liquid flow control are suitable for process connections with diverse pipe tees (inline pipe diameters DN50-DN150 and pressure rating PN25) and optional threads for direct installation (insertion). Including potable water flow switches for detecting tap water. Push-in or electrical connection type flow switches in brass or stainless steel.

  • Water Treatment
  • Potable Water
  • Heat Pumps & Compressors
DNV GL, DIN & WRAS Approved Flow Switches

DNV GL, DIN & WRAS Approved Flow Switches

Flow switches are available also for monitoring air flows (-10 to 85°C medium temperatures) with IP65 protection class to EN60730-1 (Class 1). SIKA VHX flow switches are ignition hazard assessed to DIN EN 60079-11* for use in potentially hazardous area Zone 1 and Zone 2 – with no potential ignition sources they are suitable for hazardous area flow control applications.

  • *Explosive Atmospheres – Part 11: Equipment protection by intrinsic safety “i” (IEC 60079-11:2011 + Cor.:2012); German version EN 60079-11:2012

Sika flow switches are Germanischer Lloyd and WRAS approved. WRAS (Water Regulations Advisory Scheme) is a conformance mark that demonstrates product compliance to high standards stipulated by UK water regulations.
