Section 1 Figure 1-3 GT1600 Floats (Descriptions refer to floats used in the same size tube) There are four types of floats available for the GT1600 flowmeter. Refer to Figure 1-3. Guide ribs are formed into the tube to keep the float operating in the center of the tube. The guide ribs do not follow the taper of the tube. They are parallel to the tube centerline so that the proper operating clearance for the float is maintained for its entire range of travel. The increasing annular area of the tube is in the area between the ribs. Refer to Figure 1-2. - Page 8 Section 1 Table 1-1 Specifications - GT1600 Flow Accuracy Standard: ±10%, ± 5%, ±2% Full Scale, Class 2.5 acc VDI/VDE Optional: ±1% Full Scale, Class 1.6 acc VDI/VDE Repeatability 0.5% Full Scale Capacities and Pressure Drops See Capacities Scales Transparant scale.

Page 15: Optional Equipment - Alarms & Valves
Section 1 Optional Equipment - Alarms & Valves GT1600 Alarm Contacts Meter Sizes 7 to 10 The Brooks reed switch alarm is a normally open, latching switch used in conjunction with the GT1600 glass tube flow meter for signaling high and/or low flow or a deviation from a flow setting. A magnet embedded and sealed 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 reed switch consists of a biasing magnet and hermetically sealed reed switch, which is insulated to prevent damage from mild shock and normal pipe vibration. The contact rating of the switch is very low (0.5A). An external relay is recommended for secure operation. Plus the external relay can be configured to operate as a normally open or normally closed state which provides totally flexibilty of operation. Alarm Specifications:... -

- Page 19 Alarm Contacts Meter Sizes 2 and 6 Inductive coils for high and/or low flow alarm may be mounted to the instrument to create a highly sensitive, stable and accurate device for signaling 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 Brooks can supply an approved Namur power supply amplifier/relay unit to obtain an intrinsic safe current circuit. (Please refer to Table 1-4).

Receipt of Equipment When the equipment is received, the outside packing case should be checked for damage incurred during shipment. If the packing case is damaged, the local carrier should be notified at once regarding his liability. A report should be submitted to the nearest Brooks Instrument location listed on the Global Service Network page on our website: BrooksInstrument.com/GlobalSupportCenters Remove the envelope containing the packing list. Carefully remove the instrument from the packing case. Make sure spare parts are not discarded with the packing materials. -
Page 23: Transit Precautions
Section 2 Transit Precautions To safeguard against damage during transit, transport the instrument to the installation site in the same container used for transportation from the factory if circumstances permit. Installation Location For proper operation of the GT1600 flowmeter it must be mounted within 6 degrees of true vertical, with the inlet connection at the bottom of the meter, and the outlet at the top. The use of a plumb-bob, level or other device to assure vertical positioning is recommended. -
Page 24: Section 3 Operation
Section 3 Pre-Operational Check Prior to initial start-up and each time the flowmeter is reassembled, the scale alignment should be checked. If the reference line on the tube is aligned with the reference line on the scale, the flowmeter is ready for operation. If the reference lines are not aligned, loosen the screws securing the scale and move it until the marks are in alignment. Then tighten the screws. Operating Instructions After the flowmeter has been properly installed in the process, it is ready for operation. When initiating flow, slowly open the valve to avoid a flow surge. - Page 25 Section 3 Dimension Tube Process H(orizontal) Meter type size V(er al Notes etro-fit Model inch inch inch inch inch inch inch inch 127-Low Flow NPT- H-IN / H-OUT Standard T1000 1020 8.59 218.3 0.59 15.0 V-IN / V-OUT 1024 9.84 250.0 dimensions H-IN / V-OUT...
