Description

DESCRIPTION

Blancett B1500 flow meters are precisely manufactured and calibrated instruments used in accurate rate-of-flow and total-flow measurement.

The flow meter mounts directly in the flow line and consists of a cylindrically bored housing, a flow straightener and turbine assembly, and a magnetic pickup, as shown in

Figure 1.

The magnetic pickup is located directly above the turbine, near the downstream end of the flow meter. The flow straightener and turbine assembly is retained in the housing by a snap ring and can be easily removed for cleaning and further disassembly.

Figure 1: Turbine flow meter

Blancett B1500 flow meters are provided with flow straighteners at the downstream and upstream ends. The flow straighteners diminish any turbulence created by the turbine. Other physical differences are illustrated in exploded views. See Figure 1.

Fluid passing through the meter causes the rotor and bearing to revolve at a speed directly proportional to fluid velocity. As each rotor blade passes the pickup, it varies the pickup’s reluctance, producing an output signal. Since turbine speed is directly proportional to fluid velocity, signal frequency is similarly proportional to the volumetric rate-of-flow. The output signal can be fed into various types of instruments, such as indicators, frequency converters, counters, recorders and controllers to indicate the rate-of-flow.

The Blancett B1500 flow meter is designed to provide a high frequency output voltage at the maximum of their flow range. This high frequency signal improves resolution and the standardized output permits several overlapping range flow meters to be connected in series to one indicating instrument. Data concerning extended ranges, specific output voltage and other frequency ranges is available from the factory.

Installation

INSTALLATION

1. Check the ow meter internally for foreign material and make sure the turbine rotor spins freely prior to installation.

2. Install a minimum of 10 pipe diameters of straight pipe or tube in the same size as the ow meter on the upstream side, and 5 diameters on the downstream side to avoid creating turbulence in the liquid, which can cause incorrect ow meter output. If space prohibits the use of these straight sections, install the piping to produce as straight and smooth a ow as possible.

3. Flush the ow metering pipe line. Debris such as dirt, grease, piping compounds, weld slag, rust, shavings and the like could be unknowingly contained within the diameter of the piping system. Failure to remove these contaminants may damage the internal components of the ow meter and other system components.

4. Install the ow meter with the ow arrow, etched on the exterior of the meter body, pointing in the direction of uid ow.

5. Install a mesh strainer upstream before operation of the ow meter if particles are present. See “Filtration Recommendation” on page 13.

BLEED ALL AIR AND VAPOR FROM THE LIQUID AFTER INSTALLING OR REINSTALLING A FLOW METER.

6. Start ow slowly to avoid sending a “slug” of high velocity air or vapor through the ow meter and causing it to over-speed. Start required ow after ow meter is full of liquid. Aerated liquids owing through a ow meter will result in incorrect ow rates.

7. The pipe containing the ow meter should be completely lled at all times to avoid corrosion. If a process shutdown is required where the pipe is partially or fully empty, remove and clean the meter. See “Cleaning” on page 8.

OTE:N The meter is not recommended for long periods of over-speeding. Over-speeding

increases the amount of pressure drop across the meter and significantly reduces the life of the bearing and rotor assembly. The maximum amount of over-speeding for any given meter is 150% of its capacity.

Disassembly

DISASSEMBLY

1. Firmly hold the ow meter and, using tweezers, carefully remove internal snap ring from the upstream end.

2. Use long nose pliers to grasp one vane of the ow straightener and gently pull the ow straightener and rotor assembly from the body. Use a slight twisting motion.

3. Press down on the hub to relieve spring pressure on the C-washer and remove with tweezers or thin-nosed pliers.

4. Remove hub, spring and spacer.

5. Carefully remove the rotor from the shaft.

6. Remove the snap ring from the side of the bearing and push the bearing out of the rotor. Figure 2: B1500 turbine flow meter

CLEANING

Immerse all parts, except the pickup, in a clean, filtered solvent suitable for removing residue from the liquid used with the flow meter. If necessary, use a soft bristle brush.

If there is foreign matter in the ball bearings, soak the bearings in the solvent for approximately 10 minutes and then dry with filtered compressed air. Do not use excessive air pressure.

OTE:N Do not sonic clean the bearings.

EXERCISE EXTREME CARE DURING THE CLEANING PROCESS SO NONE OF THE PARTS ARE DROPPED, SCRATCHED OR DAMAGED IN ANY WAY. DO NOT ATTEMPT TO FURTHER POLISH ANY OF THE PARTS, ESPECIALLY THE ROTOR.

Cleaning a Turbine Meter after Water Calibration and/or Service

OTE:N When cleaning flow meters, keep the body, sleeve and pickup together. The

sleeve is fitted to the body and the pickup has a protruding pin. Replacement pickups are supplied with a nut and have no protruding pin.

1. Remove the meter from the line and let all excess water drip out.

2. Fill the meter with alcohol, at least 50% Isopropyl, Ethyl or Methyl, and let it stand for 5 minutes.

3. Discard the alcohol and let the meter dry for 2 minutes.

4. Fill the meter with MIL-C-7024 Type 2 calibration uid, or similar solvent, and let it stand for 1 minute.

5. Discard the calibration uid and ush the meter with an approved uorocarbon solvent, such as Isotron.

Page 9

Reassembly

OTE:N If this procedure is not possible, make sure the turbine meter is always filled with

water when not in use, to prevent internal wetted parts from being exposed to air.

DO NOT INTERCHANGE FLOW METER PARTS OTHER THAN BEARINGS AND RETAINING RINGS. THIS PRECAUTION IS NECESSARY TO PRESERVE LINEARITY AND REPEATABILITY.

REASSEMBLY

Reassembly is the reverse of disassembly except for the following:

• On flow meters where shaft bearings are provided with a retainer, always install with the retainer flange facing upstream.

• Inspect the rotor for markings as shown in Figure 3 to indicate flow direction before assembly.

• Flow meters that have broached slots in the body for flow straightener vanes should be carefully assembled.

• Align the straightener vanes with the slots and push gently until the assembly is seated.

K-Factor

The calibration data supplied with a B1500 flow meter is shown in Figure 4. Correct application of a B1500 flow meter requires consideration of many important factors. Because of the wide variation of possible applications, detailed data for liquid flow models only is given in this manual. For special requirements, consult the factory.

Pressure Rating

Flange flow meters are rated for service pressure according to ANSI ratings for the flanges used. Operation at temperatures above 200° F (93° C) decreases the connection rating because of lowered stress capabilities of the metal.

RECALIBRATION

• Recalibration is not necessary following a cleaning operation or the replacement of bearings, snap rings, springs or spacers.

• Recalibrate the flow meter if the rotor hub, or rotor and flow straightener assembly is replaced.

• Flow meters may be recalibrated by the user if the facilities are available, or they may be returned to the factory. Yearly calibration is recommended.

• When the flow meter is set up for recalibration, allow the fluid to circulate for 5 minutes before beginning the calibrating runs.
