  • Page 6: Section 1 Introduction

    Refer to Figure 1-1. As the float moves up and down within the tapered tube, the annular area between the float and tube varies (area increases as the float rises). This gives the generic name of "variable area meter" for this measurement principle. As the flow varies, the float will move within the tube until it reaches an equilibrium position, where the tube taper creates an appropriate annular area to balance the forces of gravity and the fluids acting on the float. Refer to Figure 1-2. Figure 1-1 Principle of Operation Figure 1-2 Cross-Section - GT1600 Flow Tubes with Rib Guides Instruction Manual GT1600 Series...

    Brooks Instrument Section 1 Introduction 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.

    Brooks Instrument Section 1 Introduction 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 flexibility of operation.

  • Page 24: Section 3 Operation

    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. Bypass is a help in bringing the flow on smoothly. Avoid starting a pump to supply the flowmeter without the use of a valve upstream of the flowmeter. Instruction Manual GT1600 Series...
  • Page 25 Figure 3-1 Typical Flowmeter Piping Configuration To initiate flow through a flowmeter using bypass piping, refer to Figure 3-1. 1. Close flowmeter inlet valve (A) and outlet valve(B). 2. Fully open bypass valve (C) and slightly open control valve (D). 3. Initiate process flow. When flow has stabilized, fully open outlet valve (B), then slowly open inlet valve (A) . 4. Close bypass valve (C). 5. Regulate process flow using control valve (D). 6. If meter is left in bypass configuration, open drain valve (E) to prevent tube damage caused by thermal expansion of the process liquid. WARNING Failure to drain the flowmeter when located in a bypass loop may result in tube breakage caused by chemical expansion of the process liquid. Instruction Manual GT1600 Series...
