1. Safety Instructions 1.1 Correct Usage • The EF200 measuring system is used to measure the flow of saturated steam, superheated steam, air and water. Do not use to measure the flow of toxic, flammable or otherwise hazardous fluids. Use this system only as intended.
• Observe all local regulations governing the opening and repair of electrical devices. 1.5 Repairs, Dangerous Chemicals Warning! The following procedures must be carried out before an EF200 is sent to TLV for repair: Warning! NOTE: References to use with hazardous fluids are for customers having special permission and a signed contract with TLV for hazardous use.
-200 to +400 °C and at nominal pressures of up to 4.96 MPaG (49.6 barg). EF200 can measure the volumetric flow rate in operation and can be programmed to supply the flow rate in mass, energy or corrected volume units via temperature measurements by the internal temperature sensor.
IP66/67, Type 4X enclosure Temperature Ranges • The maximum allowable ambient and process temperatures must be observed (see 6.1.6). • Ensure both pipeline heat insulation and mounting position conditions are met (see 3.3). 172-65639M-01 (EF200) 13 Apr 2018...
A vortex flowmeter requires a fully developed flow profile as a prerequisite for measuring volume accurately. The following points must therefore be noted when mounting the EF200 in the pipeline. Pipe Inner Diameter When ordering, ensure that the nominal diameter and pipe schedule...
3.3.3 Installation Orientation The EF200 can be mounted in any direction in the piping. An arrow on the meter body shows the direction of flow. For measuring liquids in vertical pipes, the meter should be installed with an upwards flow...
Caution! Removing the transmitter from the housing support is to be carried out by qualified TLV appointed service personnel only! Caution! 3.3.7 Ensuring accurate measurements In some cases where steam is mixed with condensate, it may not be possible to obtain accurate flow rate measurements.
When installing a bypass line, use upstream and downstream valves of a type that does not disturb the flow profile, and secure sufficient length of straight pipe. Bypass Valve Direction of Flow Ball Valve Ball Valve EF200 172-65639M-01 (EF200) 13 Apr 2018...
Gaskets that protrude into the flow affect vortex formation behind the bluff body and lead to inaccurate measurement. Therefore, the gaskets delivered by TLV come with a slightly larger inner diameter than the measuring pipe.
(optional) Unit: mm Caution! Take care not to overtighten the nuts when installing the remote transmitter on piping. Caution! The transmitter housing is constructed from die-cast aluminum, therefore may be damaged. (Recommended torque: 5 N⋅m) 172-65639M-01 (EF200) 13 Apr 2018...
3.6 Transmitter Housing / Display (Mounting/Rotating) Rotating the Transmitter Housing The transmitter housing of EF200 can be rotated on the housing support up to 350° clockwise or counterclockwise to reposition the optional local display for easy reading. This is carried out as follows (see Fig. 11): 1.
If installation outdoors in an uncovered location in unavoidable, installing the optional sunshade is recommended. (This is not required when installing compact version with the transmitter oriented downwards.) Figure 13 Installing the optional sunshade 172-65639M-01 (EF200) 13 Apr 2018...

5. Operation The EF200 has a number of functions that the user can individually set according to process conditions. The display consists of max. of 4 lines; this is where measured values and/or status variables are displayed. You can change the assignment of the display lines to different variables to suit your needs and preferences.
