Vortex Flow Meter OVAL Smart EX DELTA Standard Industrial Vortex Meters for Liquid or Gas/Steam Flows

Vortex Flow Meter OVAL Smart EX DELTA
Standard Industrial Vortex Meters for Liquid or Gas/Steam Flows
This basic model of OVAL's EX DELTA vortex meter series includes options to measure liquid or gas/steam flows and intelligent functions such as self diagnostics and the capability to review and change parameters. Additional design and installation options include fixed or replaceable flow sensor, mains or battery powered unit and integral or remote indicator, with or without display.

Vortex Flow Meter OVAL Insertion EX DELTA Industrial Insertion Vortex Meters for Liquid or Gas/Steam Flows, especially in Large Pipes

Vortex Flow Meter OVAL Insertion EX DELTA
Industrial Insertion Vortex Meters for Liquid or Gas/Steam Flows, especially in Large Pipes
The insertion EX DELTA vortex meter is an economic option for pipelines greater than 200mm diameter. In new installations or retrofit, users only need to insert the probe into the pipeline. The insertion EX DELTA series includes options to measure liquid or gas/steam flows. The hottap type is particularly beneficial for in-line measurement of a continuous process or where the process flow cannot be interrupted. Additional design and installation options include fixed or replaceable sensor and integral or remote indicator, with or without display.

Vortex Flow Meter OVAL EX DELTA DIA Industrial Vortex Meters for ‘Dirty’ Fluids

Vortex Flow Meter OVAL EX DELTA DIA
Industrial Vortex Meters for ‘Dirty’ Fluids
OVAL’s proprietary diamond-shaped vortex shedding body together with the sensor location apart from the bluff body sensor results in a consistent performance in measuring dirty liquids containing materials such as scale, dust and other contaminants. Additional design and installation options include fixed or replaceable sensor, mains or battery powered unit and integral or remote indicator, with or without display.

Vortex Flow Meter OVAL DELTA Flowpet Industrial Vortex Meter for Liquid or Gas/Steam

Vortex Flow Meter OVAL DELTA Flowpet
Industrial Vortex Meter for Liquid or Gas/Steam
The OVAL DELTA Flowpet is an industrial vortex meters that can measure liquid or gas/steam flows at temperatures up to 200°C. The product line includes battery powered, remote output provided and flow switch type models.

Vortex Flow Meter OVAL DELTA Model VF Thermistor Type Industrial Vortex Meter for Gas Measurement

Vortex Flow Meter OVAL DELTA Model VF
Thermistor Type Industrial Vortex Meter for Gas Measurement
Vortex flow meters with a thermistor sensor for vortex street detection. Changes in thermistor temperature lead to changes in resistance value and a train of pulses proportional to the flow velocity. A gas purge version is available for metering gases containing dust and mist, or high or low temperature gases.

Vortex Flow Meter OVAL insertion DELTA Model VF Insertion Thermistor Type Industrial Vortex Meter for Gas Measurement in Large Pipelines

Vortex Flow Meter OVAL insertion DELTA Model VF
Insertion Thermistor Type Industrial Vortex Meter for Gas Measurement in Large Pipelines
Developed for measuring gas flow in large size pipelines, the insertion DELTA Model VF includes a thermistor sensor for vortex street detection and a probe equivalent to a 2-inch DELTA vortex meter which is inserted in the pipe to determine the actual flow rate by measuring a representative flow velocity of the process fluid passing it.

OVAL Hybrid Multirange DELTA Flow Meters Hybrid Vortex/Thermal Mass Flow Meter with Wide Flow Range for Energy Monitoring and Leak Detection

OVAL Hybrid Multirange DELTA Flow Meters
Hybrid Vortex/Thermal Mass Flow Meter with Wide Flow Range for Energy Monitoring and Leak Detection
OVAL Hybrid Multirange DELTA flow meters combine vortex technology with a thermal mass flow meter, overcoming the difficulties of measuring low flow ranges with a standard vortex meter and offering a wide flow range of 1: 700 (at 0.6MPa) with a low pressure loss.
