DVE

Product catalog summary

Overview: The document outlines the technical specifications and features of Heinrichs DVE multi-parameter Vortex flow meters, designed for monitoring the flow of liquids, gases, and steam. These meters incorporate multiple sensors to measure parameters such as flow rate, temperature, pressure, and density, ensuring high accuracy and easy installation.

Key Features:

Monitors volumetric or mass flow of liquids, gases, and steam.
Optional integrated temperature and pressure measurement for density calculation.
Real-time energy consumption calculation capability.
High accuracy with a rangeability of up to 100:1.
Available in high temperature (up to 400°C) and high pressure (up to 100 bar) versions.
Field-configurable ranges, outputs, and displays for easy installation and commissioning.
Supports HART and Modbus communication protocols.

Models and Applications:

DVE-V: Cost-effective solution for volumetric flow rate monitoring of liquids.
DVE-T: Integrates an RTD temperature sensor for measuring the mass flow rate of saturated steam.
DVE-P: Multi-parameter instrument providing volumetric flow rate, mass flow rate, pressure, temperature, and density.
DVE-M: Energy monitoring option for calculating energy consumption in facilities or processes.

Technical Data:

Measuring Principle: Vortex flow meters detect flow by measuring the frequency of vortices shed from a bluff body, proportional to flow velocity.
Accuracy: Mass flow rate accuracy for gas and steam at ±2.0% of rate.
Repeatability and Stability: High repeatability and stability over 12 months for various measurements.
Operating Specifications: Suitable for a wide range of temperatures and pressures, with adjustable response times.

Physical and Installation Specifications:

Constructed with stainless steel and Teflon-based materials for durability.
Available in various configurations for different installation requirements, including compression fittings and packing glands.
Dimensions and weights vary based on model and configuration.

Approvals and Compliance: The meters are ATEX and IECEx approved for use in hazardous environments.

Sizing and Flow Rates:

Detailed tables provide minimum and maximum flow rates for water, steam, and air across different pipe sizes and pressures.
Considerations for piping conditions and velocity ranges are provided to ensure optimal performance.

Compression Fitting Overview:

Types of Packing Glands: Various types of packing glands based on thread type and flange specifications, including NPT Male Thread, Flange Packing Glands with different pressure ratings, and DN 50 PN Flanges.
Retraction Device Inclusion: Some packing glands include a retraction device, specified for certain models.
Special Requests: Option for special configurations upon request.

Heinrichs DVE multi parameter Vortex flow meters utilize three primary sensing elements: a vortex shedding velocity sensor an RTD temperature sensor and a solid-state pressure transducer to measure the mass flow rate of gases, liquids and steam. Systems that use external process measurements may not provide adequate compensation for the fact that process conditions can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made Because the DVE is able to measure all process variables within a single...
