Operating instructions for turbine flow meter G General details Intended use This turbine flow meter has been designed and built for measuring volumes of various media featuring different viscosities, and for the storage of data so collected. The turbine flow meter is intended for installation at the end of an output hose, e.g. a hose reeler. Design and functional description The turbine flow meter is a fluid meter with electronic counter &...
G Operating instructions for turbine flow meter 1.2.1 Display LCD The meter‘s LCD display is equipped with two numeric registers and different types of display modes showing information to the user only when it is actually needed with the operation / function going on at the moment.
1.2.4 Battery compartment The meter is powered by two 1.5 V standard batteries (N1). The battery compartment is inside the body. To replace the batteries, you must remove the cover. Technical data Designation 23295 Measuring system Turbine Accuracy l/pulse 0,017...
G Operating instructions for turbine flow meter General safety instructions Information on safety at work The turbine flow meter has been designed and built in compliance with the applicable safety and health requirements of the relevant EU directives. However, hazards may result from this product if it is not used for its intended purpose or with the necessary care.
Operating instructions for turbine flow meter G Installation The inlet and outlet of the turbine flow meter are aligned in a straight axis and equipped with 1“ threads. The meter may be installed in any given position, as a fixed unit in a pipeline and/or as a mobile unit on a spigot.
G Operating instructions for turbine flow meter Output of liquid during standard operation (Normal Mode) During standard output of liquid, the meter will count and at the same time display the volume having gone through the device so far, and the resettable total (RESET TOTAL). Accidental pressing of the RESET or TOTAL button does not have any effect in this state.
Operating instructions for turbine flow meter G 5.1.2 Resetting the resettable total volume (RESET TOTAL) You can reset the resettable total only if you have reset the register of the partial volumes before. To reset the resettable total: press RESET for several seconds. The display will show the words RESET TOTAL (see fig.): You must carry out the following steps (in this order): 1.
G Operating instructions for turbine flow meter RESET TOTAL and absolute total (TOTAL) are not shown in this mode. However, the values nevertheless go up, of course. You can check after you‘re finished. Wait for the default standby mode and press TOTAL shortly. 5.2.1 Resetting partial volumes In order to reset the partial volume register, you must first complete the output of liquid.
Operating instructions for turbine flow meter G Calibration mode The turbine flow meter has a fast and precise electronic calibration mode where you simply change the so- called calibration factor (K FACTOR). There are two calibration procedures you may choose from: Simulated operation + calibration (requiring actual output of liquid to be carried out).

G Operating instructions for turbine flow meter The flow chart below shows the schematics of the display modes the LCD display may go through. In this mode, the user may press RESET and thus change from the USER to the FACTORY FACTOR . In order to confirm your choice, shortly press TOTAL while the display shows either USER or FACT.
Operating instructions for turbine flow meter G 6.3.2 Calibration during simulated operation This procedure is basically a simulated output of liquid into a calibration vessel under actual operating conditions (flow, rate, viscosity etc.). The procedure must be carried out with utmost care. Absolutely bear in mind the following points in order to guarantee proper calibration: Have your equipment properly vented before calibration.

G Operating instructions for turbine flow meter FILL LIQUID INTO CAL VESSEL Start simulated operation, but do not press any buttons yet. Simulated operation may be interrupted and continued as necessary. Continue filling the vessel until full mark is reached. It is not necessary to top out at any specific value. Set value Actual value PRESS RESET SHORTLY...
Operating instructions for turbine flow meter G PRESS RESET SEVERAL SECS This is how the meter ‚knows‘ that calibration is now complete. Before you press the button, be absolutely sure the display shows the correct value (volume of vessel). Actual value The meter will now calculate the new USER K FACTOR: This may take a couple of secs.

G Operating instructions for turbine flow meter Example: Observed mean percentage error E % -0,9 % Current K Factor 1.000 New USER K FACTOR 1.000 x {[100-(-0,9)]÷100}= 1.000 x [(100+0,9)÷100]= 1.009 If the meter displays less than the actual amount of liquid output (negative error), the new K Factor must be greater than the old one (see example).
Operating instructions for turbine flow meter G PRESS RESET SEVERAL SECS This is how the meter ‚knows‘ that calibration is now com- plete. Before you press this button, be absolutely sure the value indicated is the value you wanted to set. NONE After the following calculation the new USER K FACTOR will be displayed a few secs.
G Operating instructions for turbine flow meter Every time you (shortly) press RESET, one of the other combinations of units will be displayed one after the other (see figs.): Press TOTAL for several seconds to store the new combination. The meter will re- start and is then ready for operation using the newly selected combination of units.
Operating instructions for turbine flow meter G Proceed as follows (items correspond to spare parts list): Press RESET in order to update total volume. ■ ■ Unscrew the battery cover (item 8). ■ ■ Remove the old batteries. ■ ■ Insert new batteries.
