1. DESCRIPTION AND OPERATION
1.1 Application
EMIS-META 215 rotameters (hereinafter referred to as rotameters) are designed for measuring of
volume of smoothly changing flow of liquids and gases, including chemically corrosive mediums at fuel and
energy plants and other enterprises. Rotameters equipped with LED display can also calculate and show total
accumulated volume, % of the maximum flow, actual current value at current output.
Rotameters are installed in automatic control, adjustment and operation systems and used at variable
industries, stationary plants and pump stations.
This equipment has the following features:
- broad range of medium temperature;
- remote control of readings;
- application for chemically corrosive mediums.
Rotameters can be used for both safe and explosive environments.
Ex-proof rotameters EMIS-META 215-Ex have explosion protection called "intrinsically safe circuit” of
“i” level under GOST 31610.11-2014 (IEC 60079-11:2014) and ex-proof marking 1Ex ib IIB/IIC T4/T2/T1 Gb X
for explosive gas mediums and Ex ib IIIB/IIIC T100°C/T250°C/T420°C Db X for explosive dust mediums.
Ex-proof rotameters EMIS-META 215-Vn have explosion protection called "ex-proof enclosure” of “d”
level under GOST IEC 60079-1-2013 and ex-proof marking 1Ex d IIB/IIC T4/T2/T1 Gb X for explosive gas
mediums and Ex tb IIIB/IIIC T100°C/T250°C/T420°C Db X for explosive dust mediums.
Rotameters without outputs and LED display belongs to non-electrical equipment and have explosion
protection called "design safety” of “c” level under GOST 31441.5-2011 and ex-proof marking II Gb c
T4/T2/T1 X for explosive gas mediums and III Db c T100°C/T250°C/T420°C X for explosive dust mediums.
Rotameter of K version (oxygen application) has separate sign "Oxygen. Dangerous!". Indicator cover
is painted blue.
1.2 Structure and Operation Principle
Rotameters of general application with vertical installation on the pipeline (see. fig.1.1).

Fig.1.1 - Measuring assembly of standard version rotameter
Rotameter consists of two main assemblies - measuring and indication parts. Indication assembly can
be equipped with current output signal or digital HART for remote control of readings.
Liquid or gas inside the flow tube 7 pushes the float 3 with some force (see fig.1.2 - 1.3). Pushed by
this force the float starts to move along the flow tube. While the area between the float and the tapered tube 8
through which the medium flows increases, the drag force decreases.
At a certain position the drag force and gravity (for version G- the spring force) reaches mechanical
equilibrium and the float stops. The distance that the float passed depends on the flow speed and is submitted
to the display through the electromagnetic device. Indicator hand shows current flow speed, the LED display
shows current flow speed and total flow volume.

Medium type*
L
Liquid
G
gas
O
Oxygen
* - initially rotameters are calibrated for standard conditions Standard conditions are as follows:
liquid - water under 20° C, density 1000 kg/cbm
gas - air under 20° C pressure of 0,1013 MPa, density 1,204 kg/cbm.
To measure other medium please specify it in the order sheet.

Ft*
PTFE-teflon **
X
customized flow tube material
* - Ft version is not applicable for horizontally mounted rotameters (application Г);
** - fluorine plastic for application up to 4,0 MPa.

X
customized (various connection types under GOST, EN, ASME; please specify)
- configurations with connection S and C are not available for rotameters with flow tubes made of Ft. If you
choose S or C connection, add mounting kit MK symbol after the magnet filter.
