BROOKS Glass Tube Flowmeter GT 1000

The GT 1000 Glass Tube flowmeter combines ruggedness and simplicity in design to provide an outstanding industrial meter. End fitting materials of brass or 316 L SS (1.4404) with vertical or horizontal flanged or threaded connections, allow for versatility of process compatibility and installation.

FEATURES
• Brass or 316 L SS (1.4404) end fittings
• Flanged / threaded connections
• Horizontal / vertical connections
• Horizontal end fittings 360 degrees rotatable
• Ten-to-one rangeability
• Painted cast aluminium frame with outstanding environmental resistance
• O-Ring seal design allows tube removal without removal from the process piping
• Panel mounting options available

SPECIFICATIONS
• Accuracy classification
Standard: Class 2.5 acc VDE/VDI 3513
Optional: Class 1.6 acc VDE/VDI 3513
• Repeatability
≤ ± 0.5 % of rate
• Operating temperature limits
-18°C up to 121°C (above 93°C with pressure reduction)
• Housing
Standard: Cast aluminium. Cast components are degreased and acrylic coated.
Optional: Epoxy coated cast aluminium housing.
• Window
Polycarbonate. An ultraviolet inhibitor is added to the base resin to reduce
decay due to exposure to unfiltered sunlight.
• End fittings
Brass or 316 L SS (1.4404)
• Tube material
Borosilicate glass
• Float material
Meter size 2 - 6 : Pyrex, Sapphire, 316 SS, Carboloy or Tantalum ball float.
Meter size 7: Pyrex, 316 SS or monel ball float.
Meter size 8 - 13: 316 L SS.
For other float materials please contact us.
• O-Ring material
Standard: Viton
Optional: Buna, Kalrez or EPDM
• Scale length
meter size 2 - 6: 127 mm
meter size 7 - 10: 250 mm
meter size 12 - 13: 200 mm
• Scale inscription
Milimetre, percent of max. flow or direct reading units on a detachable aluminium plate.
• Connections
NPT or BSP female, 150 lbs ANSI B16.5 or PN 40 DIN 2527/2635, horizontal or vertical. For other connection types please contact us.

OPTIONAL EQUIPMENT
• Needle valves/Flowcontrollers
For flow rate control, needle valves or flowcontrollers may be externally piped to the inlet or outlet side of the instrument via an adapter for vertically oriented connections only. Needle valves can be supplied up to instrument size 10 (1”). We strongly advise not to use solenoid valves as these can cause pressure shocks and damage to glass tubes.
• Alarm contacts
For meter size 2- 6:
Inductive switches for high and/or low flow alarm may be mounted to the instrument to create a highly sensitive, stable and accurate device for signalling high or low flows or deviations from a controlled flow. The inductive alarm can only be used in combination with 316 SS or carboloy ball floats. The alarm points may be adjusted over the entire flowmeter range and be set so that any two contacts may be made to operate simultaneously. For hazardous area applications IndMac can supply a CENELEC approved ((EEx) ia IIC/(Eex) ib IIC) power supply/ amplifier/ relay unit to obtain an intrinsic safe current circuit.
For meter size 7- 13:
The Brooks reed switch alarm is an alarm switch used in conjunction with the GT 1000 Glass Tube flowmeter for signalling high and/or low flow, or deviation from any switch setting. A magnet embedded in the float actuates the alarm switch. The reed switch is mounted adjacent to the flow tube and is easily adjustable over the entire flow range of the instrument. The sealed switch assembly consists of a biasing magnet and hermetically sealed reed switch. The alarm points may be adjusted over the entire flowmeter range and can be set so that any two contacts may be made to operate simultaneously. The contact rating of the dry reed switch is relatively low (0.1 A), thus a relay is normally used with the alarm switch. For hazardous area applications IndMac can supply a CENELEC approved ((Eex) ia IIC/(Eex) ib IIC) power supply/amplifier/ relay unit to obtain an intrinsic safe current circuit.
