Water-based Fluid Meters

Hedland water-based fluid meters are designed to monitor fluid flow rates of water and oil emulsions. Fluid examples include glycol mixtures, water-in-oil, glycerin and other various coolants. Standard meters provide an economical solution for operators needing a quick, visual indication of flow, without the use of additional electronics. A variety of end fittings and different material types create product flexibility and material compatibility. Expansion options are available to allow integration into remote systems via electronic output.

How to Buy Hedland Flow Meters

Overview

The Hedland Flow Meter is a variable area (rotameter) instrument. A precision machined, sharp-edged Orifice is located within the piston assembly and forms an annular opening with the contoured metering cone. The piston assembly carries a cylindrical PPS/ ceramic magnet that is magnetically coupled to an external flow Indicator that moves precisely, in direct response to movement of the piston. A calibrated spring opposes flow in the forward direction. This spring decreases viscosity sensitivity and allows the flow meter to be used in any position, including inverted.

Benefits

  • No electronics needed to obtain a reading
  • Can be installed in any position / orientation without affecting accuracy
  • The most readable product in its class
  • Does not require special plumbing or accessories to stabilize turbulent flow
  • Magnetic coupling eliminates the need for mechanical linkages that wear, loosen and leak over the functional life of competitive meters
  • Custom scale options to meet exact application requirements

Features

  • Direct reading
  • Internal calibrated spring
  • 360° rotatable guard/scale
  • Easier-to-read linear scale
  • No flow straighteners or special piping required
  • Relatively insensitive to shock and vibration
  • Special scales available

MR Transmitter

MR Transmitter More Info Less Info

The MR flow transmitter further expands the Hedland variable area (rotameter) product offering by allowing flow rates and totals to be digitally displayed or transmitted via current or voltage output. The unit features non-contact sensor electronics, an electronic signal conditioning circuit and in-field compensation capabilities. Flow meter elements are enclosed within a NEMA 12 and 13 (IP 52/54) rated enclosure and is CE compliant. The large LCD display allows for extended viewing ranges and easier programming.

Water-based Fluid Flow-Alert

Water-based Fluid Flow-Alert More Info Less Info

The Hedland Flow-Alert is a variable area flow meter (rotameter) that provides a local flow indication and electronic switches to automatically signal system operators or PLCs if flow rate is below, or above, system specifications. Flow meter elements are enclosed within a NEMA 12 and 13 (IP 52/54) rated enclosure. Users can order meters with one or two Micro or Reed Switches, in normally open or closed states.

Water-based Fluid Test Kit

Water-based Fluid Test Kit More Info Less Info

Test kits enable Hedland variable area flow meters (rotameters) to provide additional system information and diagnostic capabilities. Standard flow meters are affixed with a pressure gauge and needle valve assembly, specifically designed to allow the operator to introduce a pressure load on the system. Various instruments within a system can be tested or verified against manufacturer specifications to ensure proper functionality. Instruments tested in this manner help promote fluid power safety by allowing operators to get a clear, visible indication of system health during operation, without the dangers of close contact with operating machinery.
