4.0 Gage Mount Installation

The LTM-Series can be mounted to the side of a Magtech LG series level gage using special mounting brackets and stainless steel hose clamps. When mounting the transmitter to an LG series gage the active sensor region of the probe should fall within the centerline of the process connections on the gage. If the transmitter’s deadband region is inside the centerline of the process connections the transmitter will not output an accurate measurement because the active region of the probe is too short. When placing an order for a transmitter to accompany an existing gage it is important to indicate the style of the gage, the temperature, and the center-to-center dimension.

Calibration of the probe is factory set to the center-to-center dimensions provided; however a re-ranging may have to be performed to match the probe to the desired control room specifications. See Section 7.1 “Change Range” for more details.

4.1 Standalone Installation

The LTM-Series standalone transmitter comes equipped with a ¾” mnpt compression fitting, mounted approximately 3 to 6 inches below the electronics housing. The fitting is placed in this area to ensure the transmitter is calibrated in the sensor tubes active region. Refer to the standalone drawings for a visual description of the transmitter features. Optional configurations are available upon request (2” mnpt, flanges, etc…). The magnetic float used in the stand-alone unit is designed to travel up the sensor tube with the change in fluid level. If build-up of process or contaminates should restrict the movement of the float, the transmitter sensor tube will have to be cleaned or the float may have to be replaced with one that has a larger inside diameter. The floats are designed to match the pressure and specific gravity for the process being measured and come in various materials ranging from stainless to kynar. The magnetic float can be changed out at any time to accommodate the processes being measured. The float stop, located at the bottom of the

transmitters, can be removed to allow the float to slide off the sensor tube.

4.2 General Installation Guidelines

The basic steps to installing the LTMs are:

1.Inspection of equipment: Inspect the parts that are listed on the packing slip. Make sure nothing appears to be damaged such as a broken glass from the level indicator assembly (flippers), damaged float, or a damaged transmitter. Please file a claim with the shipping company immediately if it is believed the shipment has arrived damaged and be prepared to provide pictures.

The sensor probe of the transmitter SHOULD NOT BE BENT, BOWED, OR KINKED in any way or the transmitter will not work (will most likely go into fail mode).
