Low Flow Liquid Vortex Flowmeter

This low cost vortex flowmeter features a specially developed silicon coating which allows direct contact with the medium under very harsh conditions, giving a rapid response to flow and temperature changes.  The Von Karman effect vortex flowmeter is 5 times more accurate than turbine flowmeters and benefits from high reliability with zero moving parts.

Low Flow Liquid Ultrasonic Flowmeter

The innovative design of this product provides a high accuracy, non-invasive, flow measurement device at a fraction of the cost of other current non-invasive systems. 

The unique measurement technique automatically compensates for viscosity and temperature variations.  The measurement of flow is calculated by transit time.  The flow path is designed to minimise pressure drop and, having no moving parts within, will not encourage clog or jamming.

Low Flow Liquid Turbine Flowmeter

Hall effect turbine flow sensors ideal for low flow liquid monitoring.  An economical sensor with 0.5% repeatability, unaffected by changes in system pressures makes it ideal for OEM applications.

Rugged Housed Glass Tube Flow Transmitter

Approved for explosive atmospheres, these flowmeters offer 4-20mA output direct indication with the option of alarms.  These transmitters can be ranged to suit higher flow rates than those shown.  This flowmeter also features low pressure drop and can be configured at site or factory.

Inline Ultrasonic Flowmeter for liquids

This electronic flowmeter provides a highly accurate monitoring and control solution for water-based fluids.  The flowmeter combines two built-in switch points, a 4-20mA analogue output, and a digital flow display in a single, compact unit.

Turbine Flowmeters

These turbine flowmeters are available in a wide variety of body sizes and styles, as an industrial version for generally clean applications, hygienic for food, medical and pharmaceutical applications and the pelton wheel for low flow ranges.  The flowmeters are suitable for use on lubricating or non-lubricating liquids of low to medium viscosity and are largely insensitive to density variations, pressure or temperature fluctuations.

Electromagnetic Flowmeters

The modular design of these electromagnetic flowmeters are available in two versions; the compact where the sensor and electronics unit form a single device and as a two piece remote system where the sensor and electronics are joined by a cable.  There are various possibilities of pipe flange connections available and a choice of sensor liners to suit media.  The flowmeter has no moving parts providing zero maintenance.

Differential Pressure Flow Transmitters

These DP flow transmitters offer several different methods of flow sampling;

Annubar flowmeters feature optimized performance through an innovative measuring technique.  Minimal permanent pressure loss is a feature of this design and includes an integral temperature sensor.

Flow Velocity Sensor

For flow applications where no primary measurement device is present, this ultrasonic Doppler sensor can offer an alternative to expensive civil work installing a flume or weir.  The velocity sensor and driver package provides a proportional output of 4-20mA, when coupled with a level sensor and process controller, can be used for flow rate calculation of the pipe or channel.

Ultrasonic Flowmeters

There are three versions of ultrasonic flowmeters available; portable, fixed and hazardous area approved.  They provide a huge scope of measurement capabilities and budgets. 

The battery operated portable is the ideal tool for the measurement at several locations on one site, with its in-built datalogger for capturing process data. 

The fixed flowmeters can be wall or pipe mounted, in order to provide the most cost effective solution; the permanent flowmeters can be supplied with in-built multiplexers and have the capability to measure more than one pipe simultaneously. 

The hazardous area version is ATEX approved and can be supplied as either a single or dual channel device to be able to offer maximum cost effectiveness.

Process Flow Protection Sensor

Acoustic device used to detect changes in high frequency sound emissions created by materials in motion. Instant reaction to flow rate changes provides protection to plant or warn of other abnormal flow conditions in pipes, supply lines, chutes and feed mechanisms.  The sensor listens to noise caused by minute impacts, liquid cavitation and friction within structures; making it sensitive to the slightest changes in process conditions, but also immune to auditable noise or vibration caused by machinery.  The non-invasive sensor can be installed in minutes without the need to shut down the process and the compact design means it can be fitted in the tightest of position or environments. Typical applications include blocked pipe or chute notification, pump protection and burst filter bag detection.
