SPECIFICATIONS

Accuracy: ± 5% of full scale reading.

Float Materials: Glass (black colored), 316 Stainless Steel (silver colored), Tungsten

Carbide (Carboloy- silver colored).

Fittings: Brass or 316 Stainless Steel.

O-Rings: FKM is standard, Buna , EPR are optionally available.

Valves: Built-in needle valves are available.

Maximum Service Temperature: 65°C (150°F).

Maximum Service Pressure: 700 kPA (100 psig).

Scales: Direct reading dual scales mounted interchangeably at rear of flow meter block.

Each scale has both metric and English system units displayed. Scales are mounted by
means of locating holes between the rear of the acrylic block and the yellow colored back­ing plate. Customers can easily exchange scales for different fluids, and flow rates. Extra
scales and flow meter kits are available.

Float Readings: At center of ball shaped floats.

INSTALLATION

Mounting: Flow meters are shipped ready for panel (rear) mounting, and are easily con-

vertible to partial or full “in-line” configurations (see diagram). To convert, exchange Plug
Seals and Female Adaptors correspondingly using a 5/32" hex wrench and a 1/2 open box
wrench. Panel or “in-line” mounting is through 11/16" diameter holes, using hex nuts sup­plied.

5) Recheck the Back Plate alignment.

6) Tighten fittings.

Valve option

1) Using a 1/2" open box wrench, remove top Female Adaptor.

2) Loosen the Valve Cartridge allowing the lower Female Adaptor to be
unscrewed. Do not remove Valve Cartridge from meter.

3) Remove Back Plate and Scale by sliding them to ether side.

4) Holding the desired scale align its holes with those in the Back Plate slide
them behind the Bracket.

5) Insert but do not completely tighten top Female Adaptor.

CLEANING

From time to time you may need to clean the meter. Disassembly has to be done in a clean
environment according to the following steps:

1) Unscrew the Plug Seal from the top of the unit with a 5/16" hex wrench.

2) Remove the Bumping Spring.

3) Flip the meter and let the spherical float fall out on to a clean surface. Float should
be handled with appropriate tweezers. Do not touch float with fingers. Store the
float in a clean box or bag free of grease.

No valve option:

Unscrew the bottom Plug Seal and remove the Bumping Spring.

Valve option:

First unscrew the valve cartridge using a 1/2" open box wrench. Unscrew the
bottom Plug Seal and remove the Bumping Spring.

Clean with mild soup solution; dry out with air or inert gas.

Re-assembly starts with flipping the meter up side down.

1) Re-install the Bumping Spring in the bottom cavity;
For the valve option an extra step is required:
while squeezing the spring with appropriate flat stick, insert the valve cartridge
slowly, do not over tight it!

2) Insert the Plug Seal (both Seals are the same) carefully until it is flush with the
bracket.

3) Flip the meter over;

4) Insert the Float, the Bumping Spring and the Plug Seal until it is flush with
the bracket.

5) Shake the meter, making sure the ball is floating free, without restrictions.
