<?php
$weirdFunnyKeys = [
        'PT_1', '$PT_2', 'BS_X', 'BS_Y', //etc.
    ]; 
//now it's much simpler, we can use the above to make funny things like get the values from meta:
$metaValues = [];
foreach($weirdFunnyKeys as $key){
    $metaValues [$key] = get_post_meta(get_the_ID() ,  $key, true);
}

var_dump($metaValues);
//or build this html table:
foreach($metaValues as $val){
    if ( ! empty( $val ) ) { 
        echo '<tr><td class="umbold techs">XXXXXXXXX: </td><td>' . $val . '</td></tr>'; 
        
    }
}

//or... whatever you want! You have them in an array!!! Isn't this just darn cool!!!!!!!!!!!!!!!!!!!!!!!1111

//:)

//alternatively, if you don't want to built the table in a loop:
if ( !empty($metaValues['PT_1']) ) { echo '<tr><td class="umbold techs">XXXXXXXXX: </td><td>' . $metaValues['PT_1'] . '</td></tr>'; }
