For low-flow diesel measurement, compare CE-131 at 1\u201310 LPM<\/strong> with the CE-102 digital diesel flow meter<\/a> at 7\u201340 LPM<\/strong>. For higher flows and \u00b10.2% accuracy<\/strong>, compare the CE-105 variants by flow range and size.<\/p>\n

The CE-102-C<\/strong> row belongs to the CE-103 product family; it is not the separate CE-102 digital meter. Two other rows share the CE-103-C<\/strong> label, so use inlet size and flow range to identify the required variant.<\/p>\n

\"CE-103

Which meter fits each operating requirement?<\/h2>\n

For low flow, Chintan Engineers offers CE-131 at 1\u201310 LPM<\/strong> and CE-102 at 7\u201340 LPM<\/strong> in India. Choose CE-131 if a preset quantity must trigger a valve signal. Choose CE-102 if the line needs pulse output or an 8-digit non-resettable totalizer.<\/p>\n

From our installations, an industrial tools manufacturer needed a digital display and data output for low-flow diesel monitoring. Those two functions should be checked alongside flow range; a local display alone does not provide the CE-102 pulse output.<\/p>\n

Say you need to measure 30 LPM<\/strong>. That hypothetical flow falls within both the CE-102 and CE-PDDFM-40 ranges. CE-102 has a 3\/4-inch<\/strong> size and \u00b10.5%<\/strong> accuracy; CE-PDDFM-40 has a 40 mm<\/strong> size and \u00b10.2%<\/strong> accuracy.<\/p>\n

For a mechanical readout, CE-104 has a 1-inch BSPT\/NPT<\/strong> connection and \u00b11%<\/strong> accuracy. It is designed for non-commercial use only<\/strong>. Its specified liquids include diesel, kerosene and gasoline.<\/p>\n

The CE-105 variants cover sizes from 40 mm to 100 mm<\/strong>. Each has 0.05% repeatability<\/strong>, a 10 bar<\/strong> maximum pressure and an 80\u00b0C<\/strong> maximum temperature. Match the individual variant\u2019s flow range to the line rather than selecting by accuracy alone.<\/p>\n

What display and output features should I match to the installation?<\/h2>\n

For monitoring, CE-102 provides a built-in reed-switch pulse output and a single-channel signal output. Its 5-digit LCD<\/strong> shows a subtotal, while its 8-digit<\/strong> totalizer cannot be reset. It runs on two alkaline batteries<\/strong> and provides a correction factor.<\/p>\n

The CE-131 meter with LCD controller<\/a> displays real-time flow on a backlit 3-inch LCD<\/strong>. At the preset quantity, it sends a signal to a solenoid valve; that valve is not included<\/strong>. Liquid-temperature display requires an extra temperature sensor.<\/p>\n

CE-131 uses DC 24 V \u00b18 V \/ 1 A<\/strong> supply power. Its flow sensor works at 3\u201312 V<\/strong>. The specified normally closed valve works at DC 12 V \/ 0.3\u20130.5 A<\/strong>.<\/p>\n

CE-103 offers litres, gallons, pints and quarts, with approximately 9,000 hours<\/strong> of battery operation. The CE-104 mechanical meter<\/a> has rotating wheels, a resettable subtotal and a non-resettable master totalizer.<\/p>\n

CE-105 has a litre\/gallon register. Pulse output, air elimination, counters, a set-stop counter and a ticket printer are accessory options. Specify any required accessory for the selected CE-105 variant.<\/p>\n

Use this checklist to shortlist a meter<\/h2>\n

Check the line\u2019s flow and connection first; CE-131 covers 1\u201310 LPM<\/strong>, while CE-102 covers 7\u201340 LPM<\/strong>.<\/p>\n
