REPLACEMENT OF THE REGULATOR
WITH A FLOW METER CARTRIDGE
THE NEW TRANSFORMABLE EMMETI LOCKSHIELD CAN BE COMBINED
WITH A FLOW METER CARTRIDGE
• WHILE THE SYSTEM IS RUNNING;
• WITHOUT WATER LOSS;
• SIMPLY AND QUICKLY.

NEW DOUBLE REGULATING LOCKSHIELD
EMMETI HAVE EVOLVED A NEW AND SUPERIOR LOCKSHIELD DESIGN. THIS
ALLOWS EASIER, QUICKER AND MORE ACCURATE ONSITE SETTING OF THE
CORRECT FLOW. IT IS MORE ACCURATE AT MAINTAINING THE CORRECT LOW
FLOW, WHEN SET TO A SMALL APERTURE.
YOU NO LONGER NEED TWO SEPARATE TOOLS TO ADJUST TO A SUITABLE
FLOW RATE. FURTHER, THIS LOCKSHIELD CAN BE UPGRADED ON SITE TO
BECOME AN INTEGRATED FLOW METER AND LOCKSHIELD.
ADJUST THE LOCKSHIELD AS FOLLOWS:
THE LOCKSHIELD IS SUPPLIED IN THE CLOSED POSITION.
• REMOVE THE CAP
• TURN THE CAP OVER, AND, USING THE IMPRESSION INSIDE IT, TURN
THE ISOLATOR ANTICLOCKWISE UNTIL REACHING A FULLY OPEN
POSITION.
• USE A 4 mm ALLEN KEY CLOSE THE ADJUSTMENT SCREW CLOCKWISE
, COMPLETELY, UNTIL REACHING THE END OF STROKE.
THE LOCKSHIELD IS NOW READY FOR FLOW SETTING.
• UNSCREW THE ADJUSTMENT SCREW ANTICLOCKWISE , BY THE
DESIRED NUMBER OF TERMS (PLEASE USE GRAPH ON PAGE 17).
• INSERT THE CAP AGAIN.
IT IS NOW POSSIBLE TO SEAL THE CAP INTO POSITION USING LEAD,
TAKING ADVANTAGE OF THE HOLES PRESENT IN THE FINS IN ORDER
TO FASTEN DIRECTLY TO THE MANIFOLD, PLUS MAKING TAMPERING
IMPOSSIBLE.
NOTE:
THE ISOLATOR , IS NOT USED FOR CALIBRATION ONLY FOR ISOLATION.
REPLACEMENT OF THE REGULATOR WITH A MEASUREMENT CARTRIDGE:
• CLOSE THE ISOLATOR USING CAP . REMOVE THE CLIP WITH A SCREWDRIVER.
• REMOVE THE REGULATOR USING AN ALLEN KEY AND SCREWDRIVER.
• INSERT THE MEASUREMENT CARTRIDGE AND REPLACE THE CLIP.
PLACE THE WHITE RING NUT OVER THE CARTRIDGE.

CALCULATION METHODS
HOW TO CALCULATE THE ΔP PRESSURE DROP WITH A 200 l/h Q WATER DELIVERY CAPACITY DETERMINED BY THE VALVE AND STOP VALVE, WITH A 2,5
TURNS OPENING:
1° METHOD: USE THE PRESSURE DROP DIAGRAM
Q = 200 l/h ΔP = 40 mbar
WHERE Kv STANDS FOR Q DELIVERY CAPACITY IN m3/h CORRESPONDING TO ΔP EQUALLING 1 bar: Kv = Q / √ΔP
THE RELATIONSHIP BETWEEN ΔP (BAR) AND Q (m3/h) DELIVERY CAPACITY IS AS FOLLOWS: ΔP = Q2 / KV2
2° METHOD: USE THE Kv DIAGRAM Kv = 0,98 Q = 0,2 m3/h
ΔP = 0,22 / 0,982 = 0,04 bar

LOCKSHIELDS WITH FLOW METER
FLOW REGULATION AND ISOLATION DEVICE WITH SET CALIBRATION
MEMORY AND REGULATED FLOW DISPLAY SYSTEM.
SIMPLE, DIRECT CALIBRATION BY MEANS OF INDICATOR THAT
DISPLAYS THE CIRCUIT FLOW.
THE SPECIAL DESIGN ALSO MAKES IT POSSIBLE TO CLEAN THE WIN-
DOW OR REPLACE THE ENTIRE MEASUREMENT COMPONENT WITHOUT
DRAINING THE SYSTEM.
• MEASUREMENT FIELD 0-4 l/min
• INDICATION ERROR ± 10% OFF SCALE
• MAX WORKING PRESSURE 6 bar
• MAX WORKING TEMPERATURE 90 °C
• PRESSURE DROPS Kv from 0,15 (1 l/min)
to 0,55 (4 l/min)
• MAX PRESSURE DROP (OFF SCALE) Kv = 0,9

ADJUSTMENT
THE ADJUSTMENT OPERATION IS CARRIED OUT IN THE FOLLOWING WAY:
FIRST RAISE THE WHITE RING NUT. THE ISOLATING FUNCTION IS
SUPPLIED IN THE FULLY CLOSED POSITION. CARRY OUT THE FOLLOWING
ACTIVITY UNDER FLOW CONDITIONS. NOTE, IT IS NOT NECESSARY TO
USE TOOLS WHEN ADJUSTING, ONLY WHEN SERVICING.
1. TURN THE RING NUT A, ANTICLOCKWISE UNTIL THE LOCKSHIELD
ISOLATOR IS COMPLETELY OPEN.
2. LOWER THE RING NUT A, AND CALIBRATE USING THE ADJUSTER B,
UNTIL THE CORRECT FLOW IS REACHED (DIRECTLY INDICATED BY THE
LOADING CAPACITY FLOW SCALE IN THE CLEAR WINDOW).
3. RAISE THE RING NUT A, UNTIL IT CLICKS, INDICATING THAT IT IS IN
THE CORRECT POSITION.
IT IS ALSO POSSIBLE TO SEAL THE RING NUT INTO THIS POSITION USING
A LEAD SEAL AND THE HOLES IN THE VANES C TO FASTEN IT:
• DIRECTLY TO THE MANIFOLD, PREVENTING AND TAMPERING
• TO THE FLOW METER, MAKING IT POSSIBLE TO INTERCEPT THE FLOW
WITHOUT CHANGING THE SET CALIBRATION FOR MAXIMUM OPENING.
CLEANING THE WINDOW
• TURN THE RING NUT, A, CLOCKWISE, UNTIL THE LOCKSHIELD ISOLA-
TING FUNCTION IS COMPLETELY CLOSED
• REMOVE THE WINDOW BY SECURING ADJUSTER B,
AND USING HAND PRESSURE OR A 17 mm RING SPANNER, REMOVE
THE WINDOW GENTLY.
• CLEAN THE WINDOW AND SCREW IT BACK ON.
• TURN THE RING NUT, A, ANTI-CLOCKWISE, UNTIL THE LOCKSHIELD IS
COMPLETELY OPEN
