Model HLT Transmitter with Analog Output and HART Product overview The Model HLT liquid level transmitter satisfies the demand for an analog communication interface for sightglass (bypass chamber) applications. The Model HLT transmitter provides a 4-20 ma output for most magnetic level gauge manufacturers and allows for mounting external to the chamber without interrupting the process. Model HLT transmitters are modular in design offering a selection of mounting options and pipe styles. The modularity also offers simple field replacement. Subject to local electrical codes, the sensing element and electronics can be removed from the transmitter pipe without disturbing the operation of the process saving both time and money. The model HLT transmitter uses HART communication for setup, calibration, and diagnostics. HART can be utilized via a hand-held communicator or with the HAWK setup software via a PC and HART to serial converter. The optional on-board display and keypad is also provided for local indication and programming. Features Applications Markets 4 to 20 ma Analog Output with HART No Scheduled Maintenance or Recalibration High Accuracy and Repeatability AMS Aware Explosion-proof and/or Intrinsically Safe Inventory Control Process Vessel Bypass Chamber Petroleum and Petrochemical Power Generation Specialty Chemical All specifications are subject to change.

Product dimensions and mounting HAWK offers the Model HLT transmitter configured for external mounting to most Magnetic Level Gauges (MLG) (see Figure 1 ). The Model HLT can be ordered with the standard 5/8 inch OD pipe or the optional 1/2 inch OD pipe from 508 mm (20 in.) to 3658 mm (144 in.). Stainless steel hose clamps are typically used to secure the Model HLT to the MLG. The Model HLT transmitter Measuring Range is equal to the Order Length minus the Inactive Zone. The Measuring Range should equal the measuring range of the MLG. Ensure that there are no obstructions that will limit the ability to mount the Model HLT on the MLG.

The Model HLT can be ordered with the standard 5/8 inch OD pipe or the optional 1/2 inch OD pipe from 508 mm (20 in.) to 3658 mm (144 in.). Stainless steel hose clamps are typically used to secure the Model HLT to the MLG. The Model HLT offers an optional 90 degree fitting for an MLG with both top and bottom flanges. The 90 degree fitting allows the electronic head of the Model HLT to be positioned to the side of the pipe allowing for simpler mounting. The Model HLT transmitter Measuring Range is equal to the Order Length minus the Inactive Zone. The Measuring Range should equal the measuring range of the MLG. Ensure that there are no obstructions that will limit the ability to mount the Model HLT on the MLG. 2 ft. 9 6 3 1 ft 9 6 3 0 Figure 2. Model MRA3/4 mounting, top and bottom flange Figure 2 6
