Datasheet DM-Series Turbine flowmeters

TrigasDM GmbH 2019/05 2

Turbine flowmeters are the ideal solution for measuring applications in liquids when high accuracy, very fast response times, compact design and high reliability are required with either continuous or rapidly changing flow as well as fluctuating operating temperature and pressure. A variety of end fitting options allows the measuring instruments to be easily connected to the process piping. Applications The DM-Series turbine flowmeters are suited for a wide range of applications. These include monitoring of fuel, coolants and lubricants in engine development and construction, measurement of dosing quantities in the food and pharmaceutical sector, monitoring and measurement of high-purity water in the research and development sector, diesel consumption calculations and much more. Advantages New helical rotor blades design for improved linearity and lower pressure loss. Interference-free signal transmission (no-drift, digital pulse output). Precision ball bearings for better repeatability and optimum results at low flow rates. Very wide measuring range, up to 130:1 Integrated temperature sensor in the pickoff for real time correction of the effects of temperature and viscosity changes. Miniaturized, light weight versions for installation in applications where space is limited and vibration is of concern.

Piping Configuration Turbine flow meters can be affected by the flow profile of the fluid being measured. Installation with proper up- and downstream pipe sections will minimize and even completely eliminate flow profile induced measurement errors during calibration and operation. A straight run of pipe of at least 10 times the pipe diameter in an upstream direction, and 5 times the pipe diameter in a downstream direction are recommended (see figure and table). The upstream section should be fitted with flow straightening vane. Appropriate flow straightening sets (up- and downstream) are available on request.

Inlet section and outlet section, schematic diagram

Contamination / filter

All pipe sections and components in the metering line must be cleaned prior to the installation of the flow meter. Pipe Sealants, metal shavings and slag can damage the flow meter. If the cleanliness of the fluid cannot be guaranteed, a filter should be installed upstream of the flow meter, subject to the diameter of the flow meter.

Explosion protection (ATEX)

• Pickoffs and electronics can be supplied in explosion proof versions (ATEX) on request. With explosion proof electronics, TrigasDM turbine flow meters can be used in environments as severe as Ex-Zone 1.

• The design consists of the turbine flow meter and the ATEX Pickoff. The following type of protection applies to this construction:

ATEX: II 1 G Ex ia IIC FM08ATEX0066X USA: Intrinsically Safe Class I, II, III, Division 1 GROUP ABCDEFG Class I, Zone 0, AEX ia IIC Canada: Intrinsically Safe Class I, Division 1 GROUP ABCD Class I, Zone 0, AEX ia IIC

• The turbine flow meter is installed in the hazardous area.

• The mounting of the barrier and the TriLIN is carried out in the safe area.

• Without barriers, the turbine flow meter must not be operated in the hazardous area.

• Cable lengths of up to 400 m are possible depending on the safety barrier used.
