Permasalahan utama dalam sistem metering di industri energi dan migas adalah terjadinya deviasi sinyal arus 4–20 mA pada proses konversi ke sinyal tegangan 1–5 Volt menggunakan resistor 250 Ω. Deviasi ini menyebabkan penurunan akurasi pembacaan Flow Computer, seperti yang ditemukan di PT. X dengan deviasi mencapai 0,4545%, melebihi batas toleransi Ditmet sebesar 0,25%. Penelitian ini bertujuan untuk menganalisis dan membandingkan deviasi sinyal arus 4–20 mA antara dua konfigurasi sistem metering, yaitu current splitter dengan resistor 250 Ω dan current splitter dengan sistem cascade, guna menentukan konfigurasi yang paling akurat dan stabil untuk menjaga integritas sinyal arus. Metode penelitian meliputi studi literatur, simulasi laboratorium, diskusi dengan tenaga ahli, serta analisis hasil pengujian. Hasil menunjukkan bahwa penggunaan resistor 250 Ω menghasilkan rata-rata deviasi sebesar 6,97%, sedangkan konfigurasi tanpa resistor hanya 0,14%. Sementara itu, konfigurasi current splitter cascade memberikan performa terbaik dengan deviasi rata-rata 0,1–0,2%. Kesimpulannya, konfigurasi cascade mampu mempertahankan kestabilan sinyal arus 4–20 mA dengan tingkat akurasi tinggi, sehingga direkomendasikan untuk aplikasi metering yang membutuhkan presisi tinggi tanpa menambah beban resistif pada loop.
